Hi, since your gynae did not mention that you are overweight so u shld be still ok. Just eat healthy with more vege. Now my weight mantain so yours might be the same as mine.@ 21 weeks my boy is nearly 400g and gynae say he's not overly big, still normal.
BUT I put on a lot of weight loh!! i think from normal till now my weight gain is like 8-9kg!!! I'm really really shock when I went for my check-up. I don't have a scale at home, so only get to weigh at the hospital or gynae place. I can't seems to control my eating i feel. is like when i'm eating, i dun feel like eating. When i'm not eating, i feel hungry. It seems like my BB super like carbo staff, cause I can simply eat rice without any meat or vege, cause sometime eating meat or vege i don't really feel like having them. So now i'm really trying to cut down on the rice/noodles and eat more meat, fish, vege.
