My doc is wanting to do an ultrasound on Wednesday because my stomach is measuring bigger then I’m supposed to be. I’m supposed to be 32 weeks tomorrow. He said he’s head down already and said he can feel his head when he pushes right above my vagina. This is my first baby. Anyone know what he’s looking for in the ultrasound and could he be born early? I’m also worried because I’m only 5’1 so I’m small.
