So I had my anatomy scan within the time frame. I was told everything was looked good I was told to come back in 4 wks or so for a follow up to check my uterus. So I had my appt today they said everything was fine. But now they want me to come back when I am 32 wks to make sure everything still looks fine. Has any of you has multiple ultrasounds after being told everything was fine? Or have any of you had multiple ultrasounds and found any problems?
