I think you were quite petit before pregnancy so the weight gain could be a good thing 😁. Your baby seems like a healthy weight so don't worry.
I was 18yo at 45kg before becoming pregnant. at the end of pregnancy, I was 65kg. gained 20kg in total. baby girl came at 40+4 weighing 3.9kg.
Normal. As long as your gynae says your health & baby's are fine. That's all that matters. Baby's weight is fine too and perfect!
I gained 10 kg. some mothers gained more kgs. I think it is normal. but be careful with your health always.
