I went to the doctor this week for my 18 week appt. He said my uterus was 2 fingers below my belly button. I had 16 oz. of water an hour before he felt my uterus. I went to the bathroom 10 minutes before. When I feel my uterus, it's three fingers below my belly button and that's where I've been feeling it for three weeks. I have my 20 week ultrasound Thursday, but I can't shake this feeling that the baby isn't growing and they will tell me it's way behind in growth. Irrational I know. What are your thoughts?
