oh bless your heart. I will give you my experiences, but that's all I can tell you. The Dr.s tried to Dx me for about 2 years and during that time, my husband noticed that every time I went to the ER, I was having my period. I spoke to my GI about it, and he thought that maybe it was endometriosis mimiking Crohn's. After a million different tests, they didn't find any and I don't think they actually believed it was Crohn's until I had my resection in 2006. I am premenopausal, so during the times I didn't have a period, no flares. Hmmmm...
After the resection, I haven't had flares during my periods. (about 3 last year)
Now, a few years before the stricture was bad, I had excruciating pain in my right ovary. When I called my Gyno, he said it was a cyst that had burst, perfectly normal for premenopausal women and that my body would absorb it and it would be fine. It did and I was.
I'm just wondering if this could be a cyst. Usually I think (if I can remember that far back) it happens more during ovulation that during your actual period, but I might be wrong about that.
