Blood in stool during menstrual cycle?

Everytime I am on my cycle and I enjoy a bowel movement, I have blood surrounded by the toilet, no other time, only on my cycle. Is this mundane? When I'm not on my period, in attendance isn't any blood but once I start and I have a bowel movement, at hand is blood. Do you think me have uterine prolapse could be contributing to this?

No, I think you strain and increase the flow slightly, which drips into the toilet. The blood is from your menstrual flow, not the bowels. Or if you enjoy hemorrhoids, and you are slightly constipated from the cycle, you may be straining and bleeding from that. But since you aren't mentioning pain, and would most plausible know if you did, I assume it's not from hemorrhoids. Menstrual blood will turn red on contact with the upper air, and will look red in the bowl. Blood from high in the bowel is black, and not effortless to spot. In fact, they hold special tests only just to detect it for this reason.

Need give a hand diagnosing symptoms!?

You need to see a doc and return with this checked out soon.
