20 Weeks Pregnant
By the time you are 20 weeks pregnant, your baby is starting to grow hair on his or her head! Other fetal development that typically takes place around week 20 of pregnancy includes the following:
- A protective, waxy skin covering (called vernix caseosa) is forming to protect the baby's skin from the amniotic fluid
- Delicate eyebrows are forming
- If your baby is a girl, her uterus is starting to develop
- Your baby's skin is thickening and developing layers, including the dermis, epidermis, and subcutaneous layer
- Nail growth begins.
