First off I have two questions really.1. I hear a lot of people say they have Endo and IBS. if Endo can cause D and the pain etc. isn't it really the Endo that is effection your BM's, or is it really both or am I missing something here?2. Tell me if I should look into Endo. Here's my history> I have been on Birthcontrol since I was 16. I went on because I was having severe cramps (couldn't stand up at times) and my period would last anywhere from 9-13 days then would start again in about 14 days instead of 28. The put me on the pill and had to change my medicine about 3 times, because it would help for awhile than I would start to creep back to the same way I was. I also could bleed through a Tampon and pad (always have to wear both) in about 2 hours! I have since found a brand that keeps me regular at 5-6 days and greatly has helped with the cramping and flow (though still very heavy at times) Now recently I started having D a lot, or frequent, loose stools. Could this be from Endometriosis? I also have trouble distinguishing between menstral cramps and the normal pains I have been having since my BM pattern changed. Which made me realize those pains I have through out the month are very much like cramps. However I also have some kind of stomach acid problem too I believe as I have upper stomach pain and burning. What do you guys think? Could it be Endo not IBS? I haven't really had any testing done yet, I am going to see a GI specialist Sept 9th.Sara
