I had a 28 week ultrasound today and was told that the head was measuring perfectly at 28 weeks, but the rest of the body was not. The rest of my little girls body is measuring in the 11th percentile. When they went to measure my belly I am measuring five weeks behind, at 23 weeks. Some how my stomach has gotten smaller than a month ago. Everything else seemed to be fine, my blood pressure is always perfect, the baby's heartbeat was wonderful, I feel her move all the time. I'm extremely anxious, I have to wait four more weeks until my next ultrasound. But I have three check up in between then. Has anyone else had this happen?
