What does my baby look like in week 17?
If you could see your baby’s face, you’d notice eyelashes and eyebrows starting to grow.
And if you could take their hand, you’d see they already have a unique fingerprint.
Before this point, your baby’s head was bigger in proportion to their body. Now, however, their body is starting to fill out, and their proportions are starting to even out.
The placenta continues to grow to keep up with your baby's needs. By the time you give birth it will weigh about 500g.
Your pregnancy symptoms in week 17
Do you have swollen feet? Suffering from pelvic pain or headaches?
Here’s our guide to 10 common pregnancy complaints (and how to avoid them).
Your waist will start to disappear as your womb moves up out of your pelvis and your bump becomes more noticeable. If you've been pregnant before, your bump may start showing a bit sooner than for first-time mums. Have you thought about keeping a bump diary and taking pictures each week?
How are you feeling?
You may start to feel happier and more confident as your bump becomes more noticeable and you start to feel baby move. Some women and men find that their pregnancy suddenly feels more real when they first see the baby at a scan.
You may also have more energy to enjoy getting out and about more.
However, pregnancy can make worries about money or relationships feel bigger. As many as 1 in 10 expectant mums feel stressed and anxious.
Pregnancy hormones can often be to blame, not to mention coping with health issues, worrying about giving birth and the responsibilities of parenthood.
If you’re feeling stressed and anxious, or suffering from depression, don’t hesitate to tell your midwife. They are there to talk about your mental wellbeing in pregnancy, as well as your physical health. Our mental wellbeing tool can also help you think about how you are feeling during your pregnancy and plan ahead for after the birth. You can complete your pregnancy and post-birth wellbeing plan at any point during pregnancy.
What to do in week 17
You’ll have your second scan, known as the ‘fetal anomaly scan' between 18 and 21 weeks.
The reason for this scan is to check the growth and development of your baby.
The sonographer might also be able to tell the sex of your baby at this scan, though some hospitals have a policy of not revealing this. If you'd prefer not to know whether you're having a boy or a girl, let them know so they don't accidentally tell you the gender.
‘I didn’t find out what we were expecting in my first pregnancy. In some ways waiting was excruciating but it was so exciting not knowing. We found out with our second, but I think I preferred the element of surprise the first time!’
Lucy, mum of two.
You do not need to eat for two
You may be wondering what to eat, or how much. No matter what well-meaning people might say you don’t need to eat for two during pregnancy. Your baby takes everything they need from your body, and will grow well without you taking in any extra calories at all until the last three months.
Once you reach six months pregnancy, you may need an extra 200 calories a day, which is around half a sandwich.
Are you getting enough vitamin D?
All pregnant women should take a 10 microgram supplement of vitamin D each day to give your baby enough vitamin D for the first few months of life.
Without it, there is a risk that your child will have soft bones, which can lead to rickets (a disease that affects bone development in children).

Aerobics in pregnancy
Aerobics is great for your heart and lungs and improves muscle strength. If you’ve been doing aerobics, you can carry on while you’re pregnant.
If you’re new to it, tell the instructor you’re pregnant and start with just 15 minutes' continuous exercise three times a week. Increase this gradually to a maximum of four 30-minute sessions a week.
“I exercised throughout both my pregnancies, right up until my due date. I was more tired in the second pregnancy, because I was running around after my daughter, but I always did something active because it made me feel better.”
Anna, mum of two

I am 17 weeks and 5 days. I've been feeling small movements since the very end of my 15th week; every couple of days they became stronger. The past 3 or so days the movements have been less, and I'm worried. Is everything okay?
By Midwife @Tommys on 23 Mar 2017 - 14:34
Hi , It is probably too early for the fetal movements to have formed a recognisable pattern yet and I am sure that you are aware that many women don't feel any movements until after 20 weeks. That said, you have the option to call your midwife and ask that she/he listens to the fetal heart with a sonicaid (hand held Doppler) for your reassurance. I expect that you will have an anomaly scan very soon which will be a detailed scan of the baby and placenta. This is normally done between 18 and 22 weeks. Don't hesitate to call if you require more information. Best wishes

Always have a headache and tired
By Midwife @Tommys on 16 Mar 2017 - 09:42
If you are feeling constantly tired and have headaches, it is vitally important that you visit a midwife at your local hospital. You may need to take iron if your iron levels in your blood are low, feeling tired can be asign of this.
Having a constant headache can be a sign of pre-eclampsia too, so you may needs blood taking for that too. Please take yourself in urgently to be reviewed on your local labour ward or triage. Please take good care of yourself
