Does anyone here have any experience with an abnormal chest-head ratio? The head is measuring right on dot for 20 weeks, but the chest is quite a bit smaller. They're getting me to come in for another ultrasound at 25 ish weeks.

Going in for my anatomy ultrasound tomorrow! We found out at 17 weeks that baby is a little girl:) she was kicking away but it was a just for fun ultrasound, now I haven't felt her kicking since Saturday. I felt her several times a day before, my husband even could feel her and we once could see her from the outside. I'm a little worried about the ultrasound tomorrow but praying she is alright in there, maybe just going through a growth spurt? This is my first pregnancy so I really have no idea ...
