Brittany • Mommy to a wonderful 12yr old boy, 9yr old boy 7yr old girl 6yr old girl and 3yr old girl. Due March 11th 2023 with a boy.

I am 26+5 and my belly is measuring 29weeks. I haven’t gained any weight so far. I have GD so I’m on a pretty strict diet. I have a growth scan tomorrow to see if he’s big or if it’s just extra amniotic fluid. My biggest baby was 7lbs 10oz my Smallest was 6lbs 7oz. All sugar babies.
