Girls, I wanted to ask a question: when was the last time I was at the gynecologist at 32 weeks and during the measurement of the uterus, she didn't like the size of my belly. It turned out to be smaller than normal. She even got angry. But she only prescribed an ultrasound. If it continues to be smaller than necessary, is it dangerous? Has anyone had this happen? And what did your doctors advise?
