I was in a car accident thurday evening...They took me to hospital and checked me out and everything is fine. They kept me over night to montior the baby. After test and everything they told me that she was fine..And that they were going to do an ultrasound to check her lungs/heart and everything. I was supposed to be 31 weeks 2 days the day they did the u/s but after is was done and they measure her head and everything..They told me that she weighs 4 lbs and that im 33 weeks 2 days. Is this right?
