I'm having issues with my period.. Should I see my doctor?

I have Crohns Disease and IBS, both of which are fairly under control most of the month.. But when Aunt Flow arrives, I get the usual cramps and stuff but they are followed by a searing pain in my lower abdomen and I rush to the bathroom. I then have a violent episode of diarrhea and even if I had changed my tampon (supers) an hour prior, it is soaked and has to be changed. After a few more rounds of that hell, I can practically feel my colon and sudden movement is incredibly painful. I researched a little and the same chemicals that cause menstrual cramps cause diarrhea so that's just fantastic 😞 Any advice?
