Long before I had my colon resection (removal of 15 inches, 90% of my sigmoid, due to rectal malignant tumor) in 1999, I had loose bm's before my periods. For years! In fact when I delivered my second baby in 1990, I was given an enema, despite the fact that labor pains usually bring on bm's anyway, from what the nurse said. I told her I always got "messed up" bm wise before my periods. She said that was normal for many women (and especially during labor and delivery too).
Fast forward to after my resection and trying to find some sort of normalcy with my daily bm count now (12 to 20), when I do have a period (going into the big M now, at age 52), I am real mess. Sometimes all out D.
So you are not alone.
I often feel better when I just let my body do its thing too. Trying to firm up the bm's or turn D around, just makes it all worse. It's as if my body wants to clean me out and again, if I just put up with it, I feel better, in the long run.
So what I am saying is I was this way long before a colon resection and losing my all important Sigmoid. But couple periods and PMS with having a shorter colon and no place for stool to back up in me and I am such a mess. The only good thing with me now is I seem to entering the stage where I'm not having periods every single month. I was up until 4 or 5 months ago too! Odd for my age I know, but I was still having them. When I do have a period, I just put up with all the discomfort, bloating, repeated loose stool, many, many trips to the bathroom. A few days later as my period is winding down, I am almost cleaned out and feel as if I had just had a colonoscopy prep! So that's the flip side - I have great days after a period b/c I had just come thru near-he** to get there!
Hang in there, from all I've gathered it's quite normal. For a vast majority of women.
