My last appointment at 28w, I was told baby (using fundal height) was measuring 3 weeks big and was sent for an ultrasound to make sure everything was okay. Fast forward to today, I am 32w 4d, and now being told (using fundal again) that baby is only measuring 28w and being sent for an ultrasound again to ensure everything is ok...has anybody had this happen? It's scary to think about something being wrong!!
