My last period was oct. 3rd 2010. My husband and I are trying to conceive.. I had no period November so we thought we got lucky and got pregnant. I took a pregnant test and it was negative.. I waited until the end of the month to re-take the pregnant test and it was still negative. December came and I had no period and one totally random day I was having severe cramping and bleeding with big 3 lemon size discharge balls.. Then after a few hours the cramping stopped amd so did the bleeding. Went to see a doctor and they said everything was normal.. Is almost February and I still don't have a period and today I started this dark brown discharge and severe cramping, but just for half a day.. I currently still have cramping but no longer discharge... Can ANYONE tell me anything.. Since the doctors won't even after I have explained everything and still get nothing abnormal.
