Your Baby This Week

Your baby is about 7.4cm long and their head is becoming more proportionate. Big news: bones are starting to harden, and tiny vocal cords are forming! They're moving around, maybe even sucking their thumb to practice for future feedings. Their ovaries or testes are now fully developed inside.

Your Body This Week

Welcome to the second trimester! Hopefully, the worst of your early symptoms are fading. You might spot a small baby bump as your uterus grows upward. Increased blood flow might boost your sex drive, so don't forget to drink plenty of water!

Tips for Your Partner
