Possibly losing the baby

Erica • Married with two beautiful boys. Trying to loose the weight and not get prego at this time.
Dr is drawing more blood on Friday. If the levels haven't doubled since last Friday from the ER then they will do an ultrasound to see if they can see anything. If not I may need a d&c. My cervix is still closed but I am bleeding like a period. Has anyone else had this happen but still had the baby?
