I am a 28 year old female, I have always had really bad period cramps since I was a teen, however reading online causes I have grown to be very concerned. I have only been in 2 long term relationships, and both relationships I have only done the pull out method (irresponsible I know) but thought it was fine because I never had a pregnancy scare. Now however, as I am getting older and so want children it's become quite worry some that I have never had a scare. My period comes exactly when it should every month and last the same amount of time. Could there be something wrong that I should be looking into know before it's too late?
