I had my weekly check up Thursday. I have not gained weight in the past three weeks and this time my stomach was measuring 3 cm small. I'm 36+5. They are doing an ultrasound Monday to check for igur. My last two growth scans (29 and 32 weeks) she was in the 45th percentile. Anyone else have experience with this? The doctor didn't seem concerned but I'm kinda freaking out.
