Is it normal for my baby to look this skeleton-like still at 13 weeks? Everyone else is posting their 13 week pictures and their babies heads are nice and round and have cute little noses and mine looks creepy and the head looks flat lol. My doc said ive only gained 2 lbs and im measuring small and wants to check my thyroid even though I have a HUGE appetite. Im worried my baby isnt gaining enough weight! I know Im probably just overreacting. The ultrasound tech said he looks good and hes measuring a couple days ahead even.
