15 Weeks Pregnant: What to Expect This Week

Baby's Development at 15 Weeks

Baby's ears are close to their final position, and hearing is developing rapidly. Light passes through the uterine wall and through the thin, translucent skin, and the baby can detect it even with eyes fused shut. Fine lanugo hair now covers the whole body. Legs are now longer than the arms. The skeletal system is visibly hardening, and the baby is becoming increasingly coordinated in movement.

Your Body at 15 Weeks Pregnant

At fifteen weeks many people are feeling the best they have since becoming pregnant. Energy is high, the bump is growing but still manageable, and the emotional rollercoaster of the first trimester has eased. Nosebleeds and bleeding gums are common due to increased blood volume and sensitive blood vessels. Skin stretching over the growing uterus may cause itching. Forgetfulness — sometimes called "baby brain" — is a real and extensively studied phenomenon.

Tips for Week 15

• Talk, read, or sing to your baby — hearing is developing and your voice is already familiar.
• The second trimester is the ideal window for a childbirth education class — book now.
• Research your hospital's tour options and maternity unit policies.
• Consider whether you want a doula for labour support — good ones book up months in advance.
