Re: Painful BM only during periods:[
It might be worth checking with a Gastroenterologist.
I get some IBS symptoms around my period as well with some constipation.
My GI doc recommends a high fiber diet. Probiotics can help. I also have a prescription for Miralax which draws water to the BM which softens it and helps tremendously in the ease of going. The dosage can be doubled for those really tougher times. (Miralax is OTC, but the generic script is much less expensive.)
