I am bleeding from front and back. I have already had my cycle for the month. I am also having some sort of pain in my lower left side of back that feels like a convulsing sensation. I have a history of gastro problems. What could be a cause for this? Also, earlier, I noticed my BMs were mushy and there was a lot of bright red blood in it. Now, after about 2 hrs, my BM appears normal, and there isn t any blood present that I can see except on the tissue at this moment.
