baby growing faster then normal.

Kristin • 27 married army 2 girls ( 3 & 8 ) expecting our 3rd and final princess. recent miscarriage (04/24) we found out our rainbow is due 02/13/18 :)

is this possible?? lol we went for a gender reveal scan at 15wks and 3 days along and when they saw her he was puzzled and asked me if I was sure on the gestation age. we saw her the first time when I was 8 wks and 2 days along and she was right on the money. baby girl was swallowing and very active like crabbing her cord and her face and also was waving and kicking it was amazing. but when we heard she could be further along we got curious
