The night before last I got a terrible stomach ache with cramps. I had been to the bathroom and I had diarrhea but not full blown diarrhea, sorry to be graphic but it had loose pieces of bowel, it wasn't really watery just little chunks. I took my pill at 7:40 as always it occurred a few hours after my pill. I would like to know how much diarrhea I would have to have for it to alter my birth control. I also had unprotected sex yesterday. I have had my gyno tell me that diarrhea does not compromise pills at all but I've had others tell me they do. Who is right, I'm so confused. Also the loose stools occurred 1-2 hours after birth control.
