Yes, this is normal! My pre pregnancy weight was 61kg. At the end of pregnancy was 62kg. After pregnancy (which is now) is 51kg. My baby came out at 3kg after trying to eat as much as possible at the last few weeks (gynae gave the green light to do so). As long as your baby is still growing bigger and heavier at every visit, all is good. If there is any issue, your gynae will flag it out. Not to worry! However, my gynae did tell me to try to eat more protein and gain a bit more weight previously for my own health sake.
