Odd bleeding:(

Last month I had sex with my partner and he was a bit rough and because of that I started bleeding and had a period straight after which was 10 days early. 
​This month I have intercourse with someone (2days ago) and I've started bleeding today, even though I'm not due on for another 12 days. I don't think it's a period. 
​I'm having severe cramps. ? 
​Does anyone have any advice!
