I was 14 weeks pregnant, and went to my OB for a check-up and to hear baby's heartbeat. We were unable to hear heartbeat, ultrasound showed that it had stopped developing at 13 weeks. I had a d&c the next day (April 1) . I had some light bleeding/spotting everyday since that, and then this Tuesday (June 1) I passed what the Dr. thinks to be a decidual cast. I have since stopped bleeding, but have been very tired. What could have caused the decidual cast, if my uterus had just been cleaned out during the d&c? Is it normal to be exhausted afterward?
