I recently gave birth to a son on march 7th 2012 who passed away after 9 days. I tried to breast feed for one day and wasn't successful. I still haven't started my period and it has been 3 months now. I have taken 2 pregnancy test that came back negative. And I recently had to have a coloscopy for an abnormal pap result but the results came back okay and I have a repeat pap in 3 months. I'm really concerned with me not have started my period by now. What's going on?
