The ultrasound showed the baby has a big belly (measuring in the 97th %tile). I read online this is most common with women who have gestational diabetes, but I don't have that. I'm about 38 weeks. Anyone else face this and know what could cause it? My doctor showed a little concern, but not a lot. She said it's good they are aware of this and just need to be careful during labor, but that I should still be able to deliver vaginally.
