Your baby's development
By the time you're 17 weeks pregnant, your baby is growing quickly and now weighs around 150g.
The face begins to look much more human, and eyebrows and eyelashes are beginning to grow. Your baby's eyes can move now, although the eyelids are still shut, and the mouth can open and close.
The lines on the skin of the fingers are now formed, so the baby already has thier own individual fingerprints. Fingernails and toenails are growing, and the baby has a firm hand grip.
You at 17 weeks
You'll be offered ultrasound scans in pregnancy, including the mid-pregnancy anomaly scan offered between 18 weeks and 21 weeks and 6 days. You might hear some people call this the "20 week scan".
When you're pregnant, the safest approach to alcohol in pregnancy is not to drink it at all. Your baby cannot process alcohol as well as you can, and it can seriously affect their development.
Bleeding from the vagina may be a sign of serious problems, so seek help if you experience vaginal bleeding in pregnancy.
