38 weeks today since about 30 weeks my belly has always measured a few weeks behind of my gestational age, at 29 weeks my son was 11oz and in the 50th percentile, i then had another ultrasound at 33 weeks and 3 days because my belly was measuring at 30 weeks and he was 4 pounds 8 ounces and in the 30th percentile, my appointment on the 13th of this month i was 36+6 and measuring at 34 weeks so they ordered an uktrasound that following friday where i found out my son was 6 pounds 8 ounces!! He gained exactly 2 pounds in a month and they said he was in the 39th percentile, im nlt sure what that means though they never explained it, 39th just seems so low to me!
