Anyone else seeing their baby is a week ahead of schedule as far as growth or more? At 13 weeks he was 11 cm long and the app says along with everywhere else I look he is supposed to be 2.9 inches? My ob said he is still within the normal range but that explains why I can already feel him moving at 10 weeks..I am 14 weeks today 116.5 lb now and 5.2. I'm a little worried he is going to be bigger than his dad was.. his dad was 9 lbs...I was 6.9 lbs....
