Can someone help me in this situation? 😔

Belle✨
I started taking the pill on the first day of my periods. I have been taking the pill now for officially 21 days. 
My periods lasted for 6 days, 9-10 days AFTER my periods I had unprotected sexual intercourse over the span of 2 nights. So all up prior to having sex I had taken the pill for officially 2 weeks. 
About 2 days after sex, i started experiencing spotting. But not so period-like blood, more like a light red almost dark pink colour tone. 
Anyway, it hurts like hell when I try to masturbate, like the walls of my vagina are open wounds and it's just painful putting something up there! 
I'm going to the doctors about it, but until then can anyone shed some light for me? I'm thinking am I pregnant? Or have something going on down there?Â
