I have pretty normal easy periods. 24 day menstrual cycle and period for about five days. Hardly ever cramps but if I do have them not very bad. Well recently my period started ten days early and is lasting for two weeks. I am having some of the most painful cramps I've ever had! I am not used to this. Also if I wear a tampon it fills up in about two hours but I cramp super bad. So I have mostly used pads but hardly anything is coming out. I know changes are normal but I'm just not used to it. Does this ever happen to anyone else?
