yup, me too with the periods.... I can almost pinpoint when my period is coming based on my UC symptoms. The week before I get it, I bleed more, have more frequent & looser stools. When I do get it, the bleeding lessens, the frequency lessens.... It's a pain. I think most every female on here experiences more symptoms during that time of the month, or just prior to getting their period. The worst is menstrual cramps with bad UC symptoms.... someone save me!
