I am in 20 weeks 4 days but I didn’t fell my baby kicking yet. Sometimes I only few a bit flipping inside my tummy , not sure is it her kicking or not? This is my first baby. People always make me worry when they said if I don’t feel kicking this time. My baby is not strong, not healthy. Anyone have a same problem?
