hospital visit

I had been bleeding for a whole week passed clots I was told I had had a miscarriage two days ago I went to the hospital got blood work done. Pelvic exam vaginal ultrasound and a normal ultrasound. By the time they were getting ready to let me leave the Dr said my hcg Leves are right where they are supposed to be and I still have something in my womb. They didn't check for heartbeat though. Now I have to wait till Monday to my normal Dr appointment see if I get another ultrasound and see what it is I have in my womb. What do u girls think?
