Your baby’s development this week

Your baby’s head is still quite large at this stage, but their body is starting to catch up. Their facial features are better defined as all the facial bones become more fully formed. The tooth buds are in place and their eyes are fully developed.

Your pregnancy symptoms in week 10

Not your first pregnancy? Find out how things may be different this time around.

Indigestion

Indigestion (also known as heartburn or reflux) is common in pregnancy. This is caused by hormonal changes and the growing fetus. There are things you can do to ease the symptoms, but talk to your GP or midwife if your symptoms are severe.

Stomach pain

Stomach pains or cramps are common in pregnancy. It's probably nothing to worry about if the pain is mild and goes away when you change position, have a rest, do a poo or pass wind.

But it’s important to listen to your instincts. If you are worried about any discomfort or pain you’re experiencing, or you just feel like something is wrong, contact your GP or midwife. Don’t be concerned about wasting anyone’s time. It’s always best to get things checked out.

Noticed more vaginal discharge?

It’s normal to have more vaginal discharge during pregnancy. Healthy discharge is usually thin, clear or milky white. It should not smell unpleasant or be itchy.

Speak to your GP or midwife if you are unsure of any increase or change in your vaginal discharge.

What to do in week 10

It’s likely that you’ve had your booking appointment by this point, which is your first official antenatal appointment. If not, don’t worry. It will usually happen when you are between 8 and 12 weeks of pregnancy. Contact your GP if you’re concerned that this hasn’t been arranged.

Don’t be afraid to ask your midwife anything you want to know about pregnancy. Don’t be embarrassed, they’ve heard it all before! See our answers to some frequently asked questions.

Maternity exemption certificate

Talk to your GP or midwife about getting a maternity exemption certificate. This entitles you to free NHS dental treatment and prescriptions during your pregnancy and for 1 year after your due date.

Your first ultrasound scan

You should your first routine scan at around weeks 11 to 14 of your pregnancy. Speak to your midwife if this isn’t booked yet. This can be an emotional experience as you will see your baby for the first time.

It also:

  • confirms your estimated due date by looking at your baby's size
  • see if you're having more than one baby
  • may be used with a nuchal translucency scan to check the risk of the baby having Down's syndrome, Edward's Syndrome and Patau's Syndrome.

An ultrasound scan does not harm you or your baby.  You may need to have a full bladder for your pregnancy scans because this makes the ultrasound image clearer.

Healthy Start programme

Now is a good time to find out if you’re eligible for the government’s Healthy Start programme. It provides free food vouchers and vitamin supplements if you’re on benefits, or if you’re pregnant and under 18. See if you're eligible on the Healthy Start website.
