20w5d today with my first baby and feeling huge! I started showing super early and thought for sure she was going to be a big baby! We just had our anatomy ultrasound today and baby girl is measuring perfectly and weighs 13oz! We've known the gender since 11wks and confirmed today that she is definitely a girl!. I've been feeling her move since around 18wks, and now she moves nonstop! She wouldn't give us a super great profile view and kept turning to look towards us lol. How much did your baby weigh at 20/21 wks?
