20 weeks pregnant

Week 20

Your baby is now around 22cm long with a strong heartbeat which you may be able to see during your 20 week scan. It can be a magical moment to see your baby for the first time and a relief to have your questions answered about how they’re developing.

Read on for what to expect during your appointment and to find out what may be the cause of leg cramps at this stage.

Week 20

Measuring roughly 22cm, your baby is now becoming more aware as the part of their brain which controls their senses develops. The heart is beating strongly and can easily be detected. The skin is protecting itself by secreting a thick white mucus called vernix which acts as a waterproof barrier whilst in the womb.

You’re now due to have your 20-week scan called the ‘anomaly scan’. Its purpose is to check that everything is as it should be and your baby is developing normally. It may also be the first time you get a real glimpse of your growing baby, and many mums take their partner or a friend along to share the excitement.

your pregnancy week 20

The scan takes about 15-20 minutes. During the scan, the sonographer will look for any abnormalities in your baby’s physical growth and development, and also check the position of the placenta. At some point, they may let you see your baby on the screen and point out details like your baby’s heartbeat and their growing limbs. They may also be able to tell you the sex of your baby – not all hospitals will do this, and you will usually have to ask them to tell you if you’d like to know.

If your sonographer detects any kind of problem, you will be told at once and you may be invited back for another scan. Another scan does not always mean that there is a serious problem with your baby.

If your hospital provides such a service, you may be able to buy a print of your scan picture to share with your loved ones. If any aspect of your scan is worrying you, or you have a question you didn’t get to ask at the time, our expert team of healthcare professionals and midwife may be able to provide the answers – call them on 0800 996 1000 or try our confidential instant messaging service, Live Chat.

Many mums experience leg cramps during their second and third trimesters. The extra weight you’re carrying around is bound to put extra pressure on your leg muscles. However, cramps can also occur if you’re lacking in calcium or salt in your blood, if you’re dehydrated, if you’re simply inactive for long periods of time or if your growing bump is putting pressure on your nerves. Speak to your doctor or midwife if you have any concerns.

I had my 20 week scan last thursday and it was amazing I found out that I was having a boy! As I am a larger lady they couldn't measure all of the baby as they would have liked but I am going back for another scan at 23 weeks and they should be able to see things a lot clearer. I don't mind because I can get more pictures of my Son (sounds weird to say that!)

i had my 20 week scan yesterday, and it was fab to see baby doing well! however the sonographer asked us before she started if we would like to find out the sex and we said no way, keeping it a surprise......and then at the end she said " so im 80% certain that ur having a little girl" i was gobsmacked! She realised and apologised but this is my first baby and i really didnt want to find out!!

We had our 20 week scan yesterday, it was great to see our baby on the screen again and see it in more detail, the site of the little heart beat and the tiny arms, legs and ears was amazing. Its our first child and my inlaws first grandchild so we didn't find out what we were having as we wanted it to be a surprise. My parents have 5 other grandchildren but they are as excited as if it was their first too. Can't believe that we are half way through already. He (Don't know if it is a he but I'll say he as I can't bear to call it,it) has started kicking enough for me to feel it now, but quietens down when I want my husband to feel. Soooooooo excited. Due 25th March. Good luck to all who have their 20 week scans coming up its such an amazing experience. :-)
