General information, not medical advice. Every pregnancy is different — bring questions to your OB or midwife.

Your baby at 21 weeks

Eyebrows and eyelids are fully formed, movements are becoming more coordinated, and bone marrow is now the main site of blood cell production. Taste buds are developing.

How you might feel

Kicks and jabs are getting stronger and more noticeable.

This week's tip: Get comfortable noticing your baby's movement patterns — you'll count on them more later in pregnancy.
