Has anyone ever measured just a few cm behind and had a full term pregnancy! I just had a check up and I’m within 4 cm. She measured me at 26cm and two weeks ago Another dr measured me at 28cm. So I’m having an ultrasound in two weeks to see if it’s because baby girl is low and not using enough of her space or there’s not a lot of fluid in there! Any words of encouragement or experiences this would be greatly appreciated if they were shared! I’m worried! First time mommy! Please and thank you!
