For the past 4 months of my cycles, I have had extremely heavy periods with excruciating rectal pain. I wear a menstrual cup to catch up all the blood, because tampons and heavy pads don't work enough anymore. It feels like someone is shoving a knife up my rectum. I can hardly walk and I get shooting pains that make me have to stop quickly and hold onto something. Bowel movements are painful, too. My rectum feels tight and full, almost like I have to have a bowel movement, but I don't. This pain is ruining my life. I've never had it before.

I had a laparoscopy in Feb due to a different problem and it came up clear. I also have a colonoscopy after this first started in Oct. and it also came up clear. I have seen a colorectal surgeon and my gyno many times about this problem, and neither one knows what the heck is wrong with me.

Sorry if this is too graphic, but I felt this part is very important in describing exactly what I am feeling. Today, when the pain was really bad, I don't know what made me think of it, but I felt up inside my rectum just to see if I could feel what was causing the pain. I curled my fingers forward toward my vagina, and the wall of my vagina was hard, swollen, and painful to the touch. I pushed on it, and sure enough, there was the pain and spasms I'd been feeling, the same pain I feel in my rectum. I put my menstrual cup in just to make sure, and yep, it was my vaginal wall. I could feel it through my rectum.

I am now convinced it has something to do with my reproductive organs. Can anyone tell me what might be causing this pain and pressure in my rectum? It seems to definitely be a gynecological problem, but my gyno says it isn't. Please help. Could it be fibroids or something?
