Lost my virginity using a condom, on the pill... been bleeding for 13 days after my period

I lost my virginity to my boyfriend on the Wednesday, I used a condom but I hadn't started taking the pill yet. Then 3 days later I came on my period and began to take the pill everyday. It's been 13 days since I came on my period and I still haven't stopped bleeding. After over a week of taking the pill, I had unprotected sex with him, because I thought I'd stopped bleeding, but I'm still bleeding.

Also, after the unprotected sex my vagina stung for about 10 minutes and I don't know why?

Please, if anyone could give me some advice and help, I'd be very greatful

maby your body hasnt finished its cycle, your body might finish your body's cycle and stop the bleeding, use as much lubricant as possible next time to stop the sting
