Another ultrasound?

Kait
Not that I'm complaining I just don't know why...my ob had me lay down and was surprised how much my belly had grown then measured and felt the babies position and said she thinks the baby is no longer head down and then said my belly had gotten much larger and she might have me do another ultrasound but didn't say exactly why and was so shocked about the ultrasound since we couldn't see the gender at the anatomy scan so i didn't think to ask why another ultrasound since the babies postion dosnt matter I'm already having a c section could there be another reason she's concerned and ordering another ultrasound??
