unborn baby size infographic

If you've had an ultrasound scan with First Encounters before, you may remember seeing the model that we keep in the clinic to show our visitors:

That is a model of a foetus at 20 weeks gestation. We often show it to the expectant parents who come to us for a scan, and almost without exception, they're always surprised to see how small the baby still is at that point. By 20 weeks, the mother's 'baby bump' is usually becoming fairly pronounced, and if you've ever been present during a 3D/4D scan, you'd be forgiven for thinking that babies are rather large indeed by that stage!

Watching your unborn baby on a big TV screen tends to make them seem larger than they actually are!
 
Many an expectant mother has asked us how big her baby is at X weeks, and so we thought we'd put together a handy guide to baby size  and how it changes from conception to birth. We hope that this will give you a clearer idea of your little darling's current size!
 

How big is my baby at...

  •  ...4 weeks? Less than a twentieth of an inch long and less than a twentieth of an ounce in weight. At this point, your unborn child is just a tiny embryo, no bigger than a poppy seed. 

  •  ...8 weeks? About 16mm (0.63 inches) long, or roughly the size of a single baked bean. That's more than fifteen times larger than the 4-week-old embryo, although the baby's weight has barely changed since then - we're still talking about a small fraction of an ounce at this stage. 

  •  ...12 weeks? 2-3 inches long and about half an ounce in weight. You're currently carrying a foetus that's more or less the same size as a lime.

  •  ...16 weeks? Just under 5 inches long and about 3.5 ounces in weight. You're now in your second trimester, and the baby is about as big as an avocado.

  • ...20 weeks? 6 and a half inches in length, 10 and half ounces in weight. At this stage, your foetus is a mite shorter than a carrot but weighs quite a bit more.

  • ...24 weeks? Roughly 12 inches in length and somewhat over 1 pound weight-wise. Your unborn baby is growing quite rapidly now, and their current size is roughly similar to that of a 500ml bottle of water.

  • ...28 weeks? By now, your baby should measure about 15 inches and weigh a little more than 2lbs. Picture an aubergine and you won't be too far off.

  • ...32 weeks? Nearly 17 inches, with a weight of around 3lbs 12oz. Remember how, at 24 weeks, your baby was about the size of a 500ml bottle of drink? Well, now he or she is closer to a 1.75 bottle.

  • ...36 weeks? 18.66 inches - that's just over 47cm - in length, and the best part of 6lbs in weight. By now, your baby is roughly the size of a melon.

  • ...40 weeks? Now that you're almost ready to give birth, your baby likely weighs 7-9lbs (although this varies quite a lot) and measures between 20 and 21 inches.

Pregnancy Symptoms

If you've recently become pregnant, you're probably wondering what's in store for you over the next 9 months!

To make sure you have all the details you'll need throughout your pregnancy, we've made a week-by-week list of all the most common pregnancy symptoms. Please note that every pregnancy is different, and some people may experience certain symptoms earlier or later than others (if at all), so please don't worry if your own pregnancy doesn't perfectly match the list below.

 

5 Weeks Pregnant

This is a very common time for women to find out that they are pregnant. This is a very early stage, so don't be surprised if you aren't experiencing any pregnancy symptoms just yet.

However, you may experience:

  • Fatigue - Your body is embarking on a journey that requires a lot of energy, so even at 5 weeks, you may develop a sudden fondness for naps.

  • Frequent Urination - At 5 weeks, your kidneys are beginning to expand, so you might find yourself making more trips to the loo than usual!

 

7 Weeks Pregnant

You're almost two months in, and it's probably starting to feel a little more real. That being said, it's not unusual to have few (if any) symptoms at 7 weeks - remember, it's still relatively early in your pregnancy.

Some people experience the following symptoms around the 7-week mark:

  • Acne - Your hormones are all over the place right now, so breakouts are completely normal. Just make sure you check with your doctor before using any skin treatments to combat your spots.

  • Cravings - Are you craving foods that you wouldn't normally eat? Or perhaps an old favourite seems strangely unappealing all of a sudden? This is a normal pregnancy symptom, which usually comes paired with morning sickness. Speaking of which...

  • Nausea - The dreaded morning sickness! In spite of its common name, the feeling of nausea can sadly strike at any time of day. You may experience just a touch of nausea, or you may actually vomit - in either case, this is a common side effect of pregnancy at around 7 weeks and probably isn't anything to worry about.

 

9 Weeks Pregnant

After nine or ten weeks, you'll probably have experienced most of the pregnancy symptoms that tend to strike during the first trimester. In addition to the symptoms listed above, you may now notice:

  • Headaches - Your hormones are still surging, and this can lead to headaches (which can also be brought on by hunger, dehydration and exhaustion - so make sure you're getting plenty of food, water and rest).

  • Nasal Congestion - This is perhaps one of pregnancy's lesser-known side effects. By this stage, you may well notice an increase in your body's mucus production.

  • Breast Tenderness - Your body is prepping for breast feeding and blood flow to this area is increasing, often leading to breast tenderness.

 

12 Weeks Pregnant

Week twelve is the final week of your first trimester. Your baby has now grown from a tiny cluster of cells into a foetus, and your uterus will be starting to expand beyond your pelvic bones. In addition to all of the symptoms we've already discussed, you may now be experiencing:

  • Dizzy Spells - Those pesky hormones - particularly when coupled with changes in blood pressure - may cause you to feel dizzy. Make sure you sit down or rest during dizzy spells, and always eat/drink regularly to keep your energy up!

  • Pelvic Pain - As your uterus expands, you may experience some aches and pains. It is best to avoid any heavy exercise and be thoughtful about how you position yourself - you don't want to put any unnecessary stress on sensitive regions.

 

From Here on Out...

As you head into your second trimester, your pregnancy symptoms should become less erratic. Now you can look forward to your bump getting bigger and the baby starting to kick. You will probably continue to experience some aches and pains, and you should continue to go for regular check-ups to make sure that you and your baby-to-be are both healthy.

Here are a few milestone moments to look out for later in your pregnancy journey:

  • 13-15 Weeks Pregnant: This is generally the point at which you'll need to purchase maternity clothes. Of course, you may want to buy it earlier just for the comfort it provides!

  • 20-25 Weeks Pregnant: It's around this time that you'll start to feel your baby kicking. Again, every pregnancy is different, so don't worry too much if you have to wait a bit longer.

  • Approaching Due Date: Few women actually give birth on their exact due date. Nonetheless, it's an important date, and its passing signifies that your new baby will be with you very soon!

 

If you're 8-13 weeks pregnant, why not book an earlyAssure™ scan with First Encounters? We also offer 3D/4D scans for when you're a little further along and you're ready to see what your little one looks like!

Our clinics are located in Bristol and Cardiff.

Have you ever found yourself wondering what an ectopic pregnancy is, what causes one, or what signs indicate an ectopic pregnancy? We have put together an informal guide on spotting the signs of an ectopic pregnancy, which also explains the condition in greater detail, and outlines its possible impact on future fertility.
 
What is an Ectopic Pregnancy?
 
An ectopic pregnancy occurs when a fertilised egg implants itself outside of the womb, usually inside one of the fallopian tubes, which connect the ovaries to the womb. Often it causes pain and bleeding, which may develop into a Fallopian tube rupture with internal bleeding, should the pregnancy be left untreated.
 
This presents significant health risks to the individual as the pregnancy develops, which means that it has to be removed, either using medication or by performing an operation in more serious cases. Sadly, the pregnancy cannot be saved due to the serious nature of the condition, which can be fatal if left untreated.
 
 
What is the Cause?
 
While the cause of an ectopic pregnancy isn't always clear, it is sometimes due to an issue with the Fallopian tubes, in the case that they are too narrow or have become blocked. An egg will usually spend around five days travelling down the tube and into your womb, where it should implant and develop if fertilised. In the case of an ectopic pregnancy, the egg hasn't travelled far enough when it implants, leading to it developing in the tube itself.
 
While there are certain factors which increase the risk of an ectopic pregnancy, one in three women who suffer the abnormality will have none of the known risk factors. It is important to know what these risk factors are as it may aid in identifying the condition if you are aware of your own personal risk level.
 
You could be at greater risk if:
  • You've suffered from pelvic inflammatory disease (often caused by chlamydia)
  • You've had abdominal surgery, such as appendix removal or a c-section
  • You've become pregnant using IVF
  • You've become pregnant whilst using an IUD or taking the contraceptive mini-pill.
  • You've suffered a previous ectopic pregnancy 
 
 
How Common is the Condition?
 
An ectopic pregnancy happens in around one in every ninety pregnancies in the UK, however, this risk increases to one in ten for the individual who has suffered an ectopic pregnancy before.  In 98% of cases, it will implant in the Fallopian tubes, but in some cases, the egg can implant in the abdomen, ovary, cervix or within a c-section scar.
 
 
What are the Signs of an Ectopic Pregnancy?
 
Identifying an ectopic pregnancy isn't always straightforward because the symptoms can sometimes mirror those of a period or miscarriage, causing cramping and bleeding. The symptoms may also develop gradually, or come upon the individual suddenly, with the early stages sometimes developing without any symptoms at all.
 
Some symptoms include:
  • Expected signs of pregnancy
  • Vaginal bleeding that is different from your usual period, which can sometimes be lighter and brighter in colour, or darker than usual
  • Pain in your lower abdomen/pelvis, which can be gradual or sudden, and may be on one side.
 
Signs of a severe case which has caused a rupture include:
  • Lightheaded/faint feelings
  • Diarrhoea or pain when passing water/stools 
  • Shock or collapse due to internal bleeding
  • Shoulder tip pain, which may be made worse by lying down
 
How Does Suffering an Ectopic Pregnancy Impact Future Fertility?
 
The chances of having a healthy pregnancy after suffering an ectopic pregnancy will depend on the individual, as it relates to the health of your fallopian tubes, and that of the remaining tube if you have had to have one removed. If it has been caused by a previous pelvic infection, this may have a further impact on your fertility.
 
One healthy tube means that you have a good chance of conceiving again, and six out of ten women manage to do so effectively, going on to have a healthy pregnancy. For those who struggle to conceive, IVF may be an option.
 
If you would like to try to become pregnant after suffering an ectopic pregnancy, you should first ensure that you have properly healed from the physical and emotional damage. As always, you should consult your doctor in order to gain the best advice for your personal case.
 
In the case of keyhole surgery, you should wait until you've had at least two full menstrual cycles before trying for a baby, and six months in the case of abdominal surgery. If you've taken methotrexate, you should wait at least three months before trying to conceive, to ensure that it is out of your system completely.
 
If you suspect that you may be suffering an ectopic pregnancy, see your doctor at once, or go to the hospital directly if you feel that your symptoms are becoming worse.

Back in February last year, a debate about choosing your baby’s gender was sparked by Chrissy Tiegen and John Legend revealing that they chose for their baby, Luna, to be born a girl. Understandably, this led many parents-to-be to question how this was possible and if they could do the same.
 
To answer the question: yes, choosing your baby’s gender is now possible due to the introduction of Preimplantation Genetic Screening (PGS) and Preimplantation Genetic Diagnosis (PGD). However, this only becomes an option to couples under certain circumstances. The gender selection procedure only becomes available to couples who want to avoid passing sex-linked genetic disorders onto their children, such as haemophilia in males and Rett syndrome in females. 
 
That said, in rare cases, gender selection becomes available to parents who wish to ‘balance’ their family by having a child of each gender. Hormone tests are run to check the client’s fertility, and age limits may be applied. Some clinics will not consider clients unless they are married or already have at least one child of the opposite sex they’re trying for.

Methods of Gender Selection


The most accurate methods of choosing your baby’s gender can be very expensive and typically mean the mother-to-be has to undergo invasive infertility treatments, alongside taking fertility drugs with potential side effects. 

In vitro fertilisation (IVF) is one of the main procedures which allows gender selection. IVF is a method of fertilisation outside of the womb, starting with a round of fertility drugs which help your ovaries create more than the natural amount of eggs (typically one per month). In an IVF procedure, the patient is placed under anaesthetic before the doctor inserts an ultra sound probe through the vagina to check the ovaries and follicles. A thin needle is then inserted through the vagina wall to remove the eggs from the follicles.

The next step is for the extracted eggs to be fertilised in a Petri dish. Once the eggs become embryos after 3-5 days, they are inserted back into the patient’s uterus. If you’re younger than 35 and your embryos are healthy, no more than two are usually transferred.

 

Preimplantation Genetic Diagnosis and Preimplantation Genetic Screening


The baby gender selection process happens during the IVF procedure, where one or two cells are removed from the embryo and tested for genetic or chromosomal disorders. Preimplantation Genetic Diagnosis (PGD) and Preimplantation Genetic Screening (PGS) can be used to screen the embryos and predict the baby’s gender. Parents who are hoping to avoid gender-linked disorders usually opt for PGD as the test exposes any underlying conditions the baby may have. By changing the gender of the baby, the prospective parents hope to avoid this disorder. 
 
Preimplantation Genetic Screening is typically used by patients to check if their baby has down syndrome, or are hoping to ‘balance’ their family. Both tests are almost 100% accurate at determining the gender of the baby, and any remaining embryos are frozen so they can be used in the future if the couple decides to make more children.
 
The advancement of science truly is something to marvel at, but as these methods can be expensive and invasive, waiting to find out the gender of your child can be just as exciting. Wondering what your baby will be is one of the most magical parts of carrying a child and the long awaited day of the gender reveal is a milestone in the pregnancy. Here at First Encounters, we offer gender scans from just 16 weeks, so you don’t have to wait too long either.
 

Heartburn During Pregnancy

 

Why Have I Got Heartburn During Pregnancy?

 

As your baby develops you may find that it is more than just your desire to meet them that’s burning. Heartburn during pregnancy is a frequent occurrence and can be recognised by a burning sensation that resides all the way from your breastbone to your lower throat. Many mothers experience heartburn for the first time during pregnancy and although it is quite uncomfortable, it is usually harmless. The reason heartburn occurs so frequently during pregnancy is due to the placenta producing the hormone progesterone. 

 
Progesterone is usually your friend throughout pregnancy, helping to prevent miscarriages through thickening the uterine lining, and promoting your natural health by reminding you to provide nutrients for your baby. However, this does not mean that progesterone won’t cause you pain from time to time. 
 
As it relaxes the muscles of the uterus and the valve that separates the oesophagus from the stomach, it also allows gastric acids to flow back up to the oesophagus, causing the nasty burning sensation. Your wiggling baby also contributes to your heartburn by placing pressure on the stomach and increasing the chance of acids being pushed into the oesophagus.

What Can I Do to Stop My Heartburn? 

 

1. Find out what triggers it

 
The first thing you can do is make a note each time you have heartburn of what you’ve previously had to eat or drink. Certain foods tend to directly impact heartburn during pregnancy, such as acidic foods, greasy foods, spicy foods, caffeine, fizzy drinks and chocolate. If you can figure out what is causing your heartburn, you can try to eliminate it from your diet and relieve the pain. 

2. Try to avoid big meals

 
Big meals increase the chance of heartburn, as food does not digest as well or move as quickly during pregnancy. It is better to eat several small meals throughout the day, taking your time to eat and chewing thoroughly. 

3. Take care when you sleep

 
Keeping your upper body elevated while you sleep can help stop your stomach acids from reaching the oesophagus. Try to also avoid eating anything 3 hours before bedtime, as this decreases the chance of the stomach acids reaching you even further. 

4. Try chewing gum

 
After eating, chewing gum helps eliminate heartburn during pregnancy. This is due to the chewing motion producing saliva which can help neutralise the acid. 

5. Over-the-counter help

 
If all else fails, any over-the-counter antacid which contains magnesium or calcium may help relieve you of the pain. However, you should first check with your prenatal nurse before taking anything to ensure that it is safe for you during pregnancy. 

 
If your heartburn during pregnancy continues to persist after these methods, be sure to contact your health care provider to see if there are any prescription medicines you can take to help you. Be sure to contact them immediately if you spit up blood or have dark-coloured bowel movements as this is a sign of blood in your digestive tract. We hope these tips help you relieve some of the pain and enjoy every moment of your pregnancy!

We all love a bargain, and if you're interested in booking a 4D baby scan and getting a breathtaking glimpse of your unborn baby's face, you may be tempted to visit a deals / vouchers website like Groupon or Wowcher to see what discounts are currently available online. Groupon in particular seems to be perpetually flooded with dirt-cheap 4D ultrasound packages, with providers sometimes cutting their prices by 50% or even more in the hope of filling up more scan slots.
 
However, before you book a discounted 4D scan through a Groupon or Wowcher deal, here are some things you should take into consideration:
 

Many of the scan providers on Groupon are fairly new companies.

Offering a heavily-discounted scan package through a website like Groupon is a popular way for new scan providers with no established market presence to 'get the word out', as it were. An eye-catching offer can be a good way to get people talking about your company, and the hope is that customers who get the cut-price package will come back later for a full-price scan and/or recommend the clinic to their friends and family members in future.
 
The problem for customers, however, is that brand new companies have no track record by which to judge them. Established scan providers tend to have lots of reviews online, but when you go to a recently-opened ultrasound clinic that's using Groupon and Wowcher to drive that initial burst of bookings, you may not have any way of knowing whether they are able to provide a safe, satisfactory scanning experience using the right methods and equipment. This could mean that the sonographer is unable to capture good-quality footage of your baby, and in the worst cases, it could even put you / your baby in danger (e.g. from electric shocks).
 
 

Scan time may be very limited, and you may not be offered a re-scan.

We've found that many providers who sell their scan packages for reduced prices compensate for this by packing as many scan slots into the day as possible. This means that each customer's scan period must be rigidly adhered to and that's not always conducive to a satisfactory scan experience. For example, if the company has allotted 10 minutes for your 4D scan and the sonographer finds upon commencing the scan that your baby is facing the wrong way, you may not have time to go for a walk and try again because this would cause you to overrun your 10-minute window and cut into the next customer's appointment.
 
When this happens, most companies would offer a re-scan on a different date, but the fine print on Groupon offers often includes a stipulation like this:
 
"If satisfactory imagery cannot be obtained, no re-scan will be offered."
 
This means that you would have to pay full price for another appointment if your first, discounted appointment did not yield satisfactory scan footage / photos.
 
 

Why choose First Encounters?

Here at First Encounters Ultrasound, we never run offers through websites like Groupon or Wowcher - all of our scan packages are priced as seen here. However, we believe that we provide an experience that's far superior to any you'll get through those websites. Here are just a few of the reasons why:
  • All of our scans are performed by qualified, experienced medical professionals.

  • We only use certified safe equipment from GE Healthcare.

  • Our appointment slots always include time for multiple scan attempts.

  • We always offer a complimentary re-scan if satisfactory imagery cannot be obtained on your first scan date.

  • Our reputation is second to none - just look at the reviews on our Facebook page!
