So... I have board exams and my period is about to start. My period cramps hurt a lot so I was thinking of trying pain killers this time I mean you know I need to study as these are really important exams. I'm 16 and what kind of pain killer would be good enough to relieve pain? ( I have never had any pain killers and I only want to try this once for my exams)
