30 weeks

Yulin, you may already be experiencing some hardening and contracting of your abdomen. What you're feeling are called Braxton-Hicks contractions. These early contractions usually last about 30 seconds. Some you may not feel at all, while others may become uncomfortable for you

Your Baby

Your baby now weighs around 3 pounds and is about 17 inches from head to toe. An ultrasound image may show your baby yawning or even sucking its thumb, and you may also notice that your baby does not move at all during your Braxton Hicks contractions. This is because your muscles tighten and constrict his or her movement. By now your baby is probably more used to Braxton Hicks than you are.
