At nineteen weeks pregnant, your baby’s lungs are developing, and this week her windpipes will start to form. You might also start to feel her moving this week and your 20 week scan is not too far away. Here are any symptoms you can expect and what your baby and your body are doing at 19 weeks.

How big is my baby at 19 weeks pregnant?

Your growing baby is now around six inches long, which is about the size of a mango! She’s had a bit of a growth spurt this week and weighs about half a pound now.

What’s my baby doing at 19 weeks pregnant?

This week, fat is starting to develop on your baby’s body, although she’ll still look pretty skinny. She’ll also be covered in a waxy substance, medically referred to as vernix caseosa. This is greasy and white and made up of hair, oil and dead skin cells. It might not sound too appealing, but it does an important job protecting your baby’s soft and sensitive skin from the amniotic fluid she’s living in. In fact, without the vernix, she’d look like she’d been in a bath for nine months! Most babies will lose their vernix coating before they are born, but some babies, especially those born early still have some and it will be wiped off by your midwife after birth.

At week 19, the pigmentation in your baby’s skin is also beginning to develop, thanks to melanocytes – skin cells that produce the skin pigment melanin – and this will continue after he’s born and well into childhood.

"By now, your baby is also moving around a lot, so you can expect to start feeling those tiny flutters anywhere between 18 and 22 weeks. That said, every woman and every baby is different, so if you’re not feeling any movement, this isn’t a sign anything is wrong."

By now, your baby is also moving around a lot, so you can expect to start feeling those tiny flutters anywhere between 18 and 22 weeks. That said, every woman and every baby is different, so if you’re not feeling any movement, this isn’t a sign anything is wrong. Some of it is down to your size, as the thinner you are the more likely you are to feel those movements earlier. It’s also largely down to your baby’s position – if she’s facing into your body, it’s much more difficult to perceive these early movements. Don’t worry if you haven’t felt anything yet – you will do in a few weeks' time!


8 common symptoms to look out for at 19 weeks pregnant:

Leg Cramps1 of 8

1) Leg cramps

Unfortunately you'll feel leg cramps more when you’re lying in bed at night. No one really knows why they choose to interrupt your much-needed sleep, but when those painful leg cramps do strike, try straightening your leg and gently flexing your ankle and toes towards your shins.

Stuffy Nose2 of 8

2) Stuffy nose

As we mentioned in previous weeks, those pregnancy hormones can often cause swelling in your nasal passages which makes it hard to breathe. Try unblocking your nose by gently closing one nostril and blowing out of the other.

General Aches3 of 8

3) General aches

This can be anything from abdominal aches and pains to hip or groin pain. Round ligament pain, the discomfort in your lower abdomen, has been going on for a few weeks now. It is because of the way your muscles are stretching to make room for your baby. Hip pain might make sleeping at night difficult so try sleeping on your side with a pillow between your knees or go all out and buy a pregnancy pillow.

Constipation4 of 8

4) Constipation

This is a normal side effect of pregnancy, but it’s worth taking a look at any supplements you’re taking as those including iron can often make it worse. It’s also worth talking to your GP or midwife, as they’ll be able to help.

Increased Appetite5 of 8

5) Increased appetite

Constantly hungry? This is a sign your baby is growing, so keep your handbag stocked with healthy snacks!

Lightheadedness or dizziness6 of 8

6) Lightheadedness or dizziness

Lightheadedness can occur because your uterus puts pressure on your blood vessels or because the growth of your baby makes crowds your chest and lungs meaning you have less oxygen pumping around. Dehydration and hunger are obvious causes so make sure you eat and drink water regularly.

Blurred Vision7 of 8

7) Blurred vision

Although this sounds super scary, rest assured it is a common and normal side effect, caused by a build-up of fluid in your eyes. Try not to worry too much, but make sure you mention it to your GP or midwife.

8) Backache8 of 8

8) Backache

More aches? Yep, sorry. Your uterus is growing and putting extra pressure on your lower back. If you are suffering with back pain, make sure you take it easy - lay off the pregnancy exercise and try not to lift anything too heavy.
