I am 18, a virgin, and I've been getting my period since I was 11. But lately for the past like three months its been completely out of whack. I skipped it one month, and then the next month it was super light. So Light I only used one tampon for a whole day for one day, and then the next just pantie liners, but I mostly noticed blood on the toilet paper when I went to the bathroom (sorry T.M.I i know) I should have started this month's today. I just dont know whats going on. I cant get to sleep anymore. I am pretty stressed over preparing for my summer abroad, and I started college this year, so I have gained 'the freshman fifteen" extra weight. But when I say I cant sleep I mean I feel lucky if I get five or six hours. So basicallly-what is going on?
