When I was 6 weeks my GYN recommend hormones for 2 weeks because something was low in my labs, then at 8 weeks I had a small bleeding I went to the hospital and the baby was fine. They told me not to lift weight and no sex. Then when I was 16 weeks did ultrasound and lots of labs and they said the baby was fine, but the free beta hcg was not normal. (36.3 (ng/ml) mom 4.38 and %ile 99, she said that I might develop preeclampsia or the baby was going to be small, I m 35 y/o and 165 lbs. After that they did 3 more ultrasound and they say everything is fine. Is there something I should worry about
