With my first child, my daughter, I was 98lbs pre-pregnancy and gained 45lbs. This time around, I was 118lbs pre-pregnancy and as of 32 weeks, have only gained 16lbs. Is this normal? I feel like I should gave gained much more by now. My belly is measuring right on track but I'm really worried my baby is going to be too tiny bc im not gaining enough weight. Advice? Suggestions? Thank you!
