I started my period the 7th of November. My period has changed. It used to start the 12th every month.  My period before wasn't bad at all. No cramping or any sort of pain. Just acne. Well, now my period is heavy. I blood clot a lot, huge ones. I throw up and feel as if I have the flu the first two days of my period. I'll be really cold. And then the rest of my period I have horrible cramps and I bleed so heavily. My period has yet to stop. I've been on my period for 10 days now. I got Birth Control to see if it'll help but I can't start it until Sunday.
