I am 3 months 10 days pregnant. i still have not gained weight in fact lost 500 gram last month. could you please recommend what should i do? worried

Relax...: Many women in the first trimester don't feel like eating. The are nauseated and sometimes vomit making it hard to gain weight. The good news is that a lack of weight gain in the first trimester won't harm your baby. Most of the time, weight gain picks up in the second trimester--especially after 20 weeks. Concentrate on a healthy, balanced diet instead of the bathroom scales! Best Wishes!
