Week 17 – your second trimester

It could just be wind – but those funny feelings in your belly might be your baby moving. This is a major milestone and a highlight of many pregnancies. Right now, you won't be able to tell exactly what your baby's up to. But soon you could be feeling every kick, punch, hiccup and somersault.

There's lots more happening this week too…

What's happening in my body?

Week by week, your baby's getting bigger, and so is your placenta, which is feeding your baby and also removing waste. By the end of your pregnancy the placenta will weigh around 500g, which is as heavy as a packet of pasta.

Your waist will start to vanish as your womb moves up and out of your pelvis. This will make you look more obviously 'pregnant' and, with any luck, you'll start to 'bloom' too. Many women look and feel amazing when they're pregnant. They have glossy, full hair (as hair loss is slowed down) and radiant skin (caused by a boost in blood volume and hormones).

However, everyone's different, and some women feel unattractive and overwhelmed by their changing body, the responsibility of having a baby and the strain it can put on relationships. Around 1 in 10 women feel stressed or anxious during their pregnancy, and your hormones can make even small problems feel so much worse than they really are. If you feel sad or worried, then talk to your doctor or midwife – there's a big support network out there for you.

A moving experience

Have you felt your baby move yet? Many women spot the first signs of movement at 18 to 20 weeks, but it could be earlier than this.

Inside your baby belly, you might feel:

  • bubbling
  • fluttering
  • rolling

This is known as 'quickening' and it's a reassuring sign that your baby is thriving. In a few weeks, the signs will be much more obvious. You might even be able to tell the difference between punching and kicking. Don't worry, it doesn't hurt, it just takes you by surprise, and it's very strange to see your belly move as a little foot kicks out!

Share the experience with your partner and let them place their hand on your bump when the baby's moving.

You might find that your baby moves more…

  • after meals

  • when you listen to loud music

  • when you rub your tummy and talk to your baby

  • when you really, really want to go to sleep!

See if you can work out any patterns. You can watch a video about what to look out for here.

Stressed by stretch marks?

At some point, you might notice red or purple streaks over your stomach and breasts. You could also spot them on your bottom and thighs. These are stretch marks and affect up to 8 in 10 women. They are usually caused by hormones and your skin stretching more quickly than it would like to. They usually fade to silver and become much less noticeable in the months after the baby's born.

You can buy all kinds of 'miracle' creams, but your best bet is to gently apply an unscented moisturiser when the lines appear… and wait for time to work its magic.

Second trimester pregnancy symptoms (at 17 weeks)

You may be getting a few pains and niggles as your bump gets bigger. Your symptoms should be manageable, and if they're not, talk to your doctor or midwife.

Your signs of pregnancy could include:

Tommy's, the baby charity, has a further list of common symptoms.

What does my baby look like?

Your baby, or foetus, is around 12cm long, from head to bottom, and weighs around 150g. That's roughly the size of a pomegranate and the weight of a ball of mozzarella. The baby's skin is wrinkled and there's a lot of fattening up to do. By the end of your pregnancy, your little one will be much plumper and will fit into their skin better, although they may still come out looking rather creased.

The big news of the week is that you may start to feel your baby move.

Plus…

  • your baby's eyes can move, although they'll stay shut for now
  • they can react to loud noises
  • their mouth can open and close
  • fingernails are starting to grow

Your baby will have their own unique fingerprints. Even identical twins have different fingerprints.

Action stations

Have you decided where you'd like to give birth? Read more about choosing a hospital, midwife-led unit or home birth. Talk to your doctor or midwife about your local options. It's a big decision but you can always change your mind later.

This week you could also…

You don't have to tell your employer for several more weeks, but as soon as you do, you will have maternity rights and can attend antenatal appointments during paid work time. You can also ask for a risk assessment of your work place to ensure that you're working away in a safe environment.

It's a good time to tone up those muscles 'down under'. Gentle exercises can help to prevent leakage when you laugh, sneeze, cough or jump around on your baby's future trampoline. Get the muscles going by pretending that you're having a wee and then stop the 'urine' in midflow. ”>Visit Tommy's for more ideas.

Ask your midwife or doctor about antenatal classes in your area, as they get booked up very quickly. You could also contact your local branch of the National Childbirth Trust. Why not ask your partner to go with you? Even if you've had children before, and been there, done that, they're still worth going to, as you can meet other parents-to-be. Also, don't expect this pregnancy to be just like your others – your baby could have other ideas.

Do your best to stop smoking, give up alcohol and go easy on the cappuccinos. We know that's easy to say but hard to do. Ask your midwife or GP for support.

During the winter, consider taking a daily dose of vitamin D. It's recommended that you take 10 micrograms every day when you're pregnant and breastfeeding. Find out if you're entitled to free vitamins.

Get moving! It's recommended that pregnant women do 150 minutes of exercise throughout the week. You could start off with just 10 minutes every day. Perhaps take a brisk walk in the park or go for a swim. If you start any classes, make sure the instructor knows that you're pregnant. Don't overdo it though – listen to your body.

Don't eat for two! Eat for you. You don't need any extra calories until the third trimester, which starts in week 28. Try to eat healthily, with plenty of fresh fruit and veg, and avoid processed, fatty and salty foods. You may be able to get free milk, fruit and veg through the Healthy Start scheme.

This week's treat

Enjoy a soothing head massage. You don't have to splash out at a fancy spa. You don't need special oils either. Just ask your partner, or a friend, to gently massage your scalp and neck while you sit upright on a chair. Research shows that regular head massages can reduce headaches by easing stress and relaxing the muscles that go into spasm.

If you get really painful headaches, then talk to your midwife or doctor, just in case there's an underlying problem.
