2nd trimester · Week 15

15 weeks pregnant

Bones harden and legs catch up

Ossification continues and the legs grow quickly. Eyes are still fused shut. You might notice a firmer lower belly, or still look unchanged.

These are averages; every baby grows at their own pace.

How is your baby developing at 15 weeks?

Taste buds are forming. The fetus can move all limbs, though you may not feel it yet — especially in a first pregnancy. Average length is about 10 cm; weight is often near 70 g.

What changes in your body at 15 weeks?

Gums may bleed when you brush (pregnancy gingivitis). Nosebleeds can continue. Some people get a darker linea nigra later; pigment can begin now.

Tips for this week

Soft-bristle brushing and a dental check are useful; tell the dentist you are pregnant. Iron-rich meals plus vitamin C can help absorption if you are not nauseated. Dizziness when lying flat on your back is more a later-pregnancy issue, but roll to the side if you feel unwell.
