Second Trimester 15 weeks pregnant

Pregnancy Week 15 - Baby Responds to Light & Taste Buds Form

At 15 weeks, your baby is about the size of an apple. Taste buds are forming, and your baby may sense light through closed eyelids. The skeletal system is continuing to develop, and your baby is becoming more active inside the womb.

Baby Development This Week

Your baby's taste buds are forming, and they will soon be able to taste the amniotic fluid, which changes flavor based on what you eat. Your baby may respond to bright light shining on your abdomen by turning away. The bones are becoming harder, and the skeletal system continues to ossify. Your baby's skin is still very thin and translucent, with blood vessels visible underneath. Eyebrows and hair on the head may be starting to grow.

Changes in Your Body

You may be feeling more like yourself again as second-trimester energy kicks in. Some women start to feel their baby move around this time, though first-time mothers usually feel it later. You might experience nasal congestion, nosebleeds, or bleeding gums due to increased blood flow. Your center of gravity is shifting as your belly grows. Some women develop carpal tunnel syndrome due to swelling that compresses nerves in the wrist.
