I have noticed my pain level is much worse at my time of the month. I think it makes sense, because even those who do not suffer with pain disorderes have issues at that time. I guess for us it's just intensified. I used to be on birth control. I took it for about 8 years after the birth of my daughter. it did greatly reduce my pain during my period. The only reason I stopped taking it was because I was concerned with risk of heart disease with long term use. I have learned that when it is my time of the month I just take it extra easy and try not to kill anyone.
