Bleeding from rough sex or period?

Emma

so a few days ago, I had some really rough sex and the next day, I find out that I've bled all over the sheets. it wasn't my first time having sex or my first time bleeding after sex. usually the bleeding stops pretty quickly but this feels like a period. I've got cramps and I've been bleeding for days. also, my period is supposed to be two weeks later, so could rough sex trigger an early period?
