I missed my pill on 7th july, but carried on taking in from 8th onwards. On the 10th I had sex with my boyfriend and used a condom to be safe. During sex i had the most painful orgasm...It's never hurt before, I was in agony. Since then I've had faint cramps which have been feeling more and more like tight tension and today 12th july, I have brown discharge. I'm 20 and not due my period for another week..I've never had brown discharge this early before.
