Week 15 of Pregnancy

Week 15 is in the growth phase. Bones harden, muscles strengthen, and movement patterns become more coordinated. Sensory systems (hearing, touch, and light response) improve, and body proportions become more balanced.

Your baby is now practicing breathing motions and swallowing amniotic fluid. This trimester is often when many mothers begin to feel stronger fetal movement and more predictable energy.

Many mothers feel better energy in week 15, but round-ligament discomfort, backache, heartburn, and nasal congestion may appear. Skin changes and mild swelling can also begin.

Supportive footwear, posture care, hydration, and regular light movement often improve comfort. Report persistent headaches, vision changes, or sudden swelling to your provider.
