I am about 3 1/2 months pregnant and have been very constipated. At first I would have a little rectal bleeding after having a bowel movement. For the last month or so, I have been having the rectal bleeding, but also having a decent amount of vaginal bleeding. I know that it is coming from the vagina. The first time it happened before I realized it was associated with the bowel movements I was seen by the doctor and was told everything with the baby was ok. (the bleeding had already stopped by then). Any ideas about what would cause vaginal bleeding after a bowel movement?
