Why is my menstrual cycle lasting so long?
i am 16 and my period has been going on for 3 to 4 weeks now. maybe more. it is very irregular. one day its heavy and the next its not. And it will skip days. for example, i can have it for a week and then it will stop for a few days and then i will have it for 2 weeks. i just want to know whats wrong and how to fix it.
