Since 2 months, for around 3-4 times I had blood in my stool without any pain. But since last 20-25 days I am experiencing cramps in my stomach almost everyday. I thought it will end with the next period cycle but it got more severe. I am not able to understand the problem., is it related to blood in my stool or menstruation cycle. Kindly help me out, as without knowing the problem I can't help myself to cure it.
