Went for an ultrasound today and the Dr said the baby is measuring small. But I am measuring just right. I'm 19 weeks 1 day. I've only gained 2 lbs in 4 weeks. Getting referred to a different office who specializes in this kind of stuff. Has anybody had this happen and everything be fine or not. Want stories from both sides. This is my third pregnancy only one living. Wishing my rainbow baby is just going to be small. But would love to hear all possibilities.
