4 months pregnant
At 4 months pregnant (weeks 14 to 17), you're in the second trimester. Your baby is about the size of a pomegranate, and many women feel their best now, with more energy and less sickness.

Your baby at 4 months pregnant
Your baby can now squint, frown and suck its thumb. Fine hair called lanugo covers the body, and the skeleton is hardening from cartilage into bone. Your baby can sense light and may start to hear sounds by the end of the month. Fat stores begin to build, and each fingertip has its own unique print. Your baby is about 13 cm long from head to bottom.
By the end of the month:
| Size | About the size of a pomegranate |
|---|---|
| Length | about 13 cm head to bottom |
| Weight | about 140 g |
