Me and my boyfriend had sex, without a condom. He only inserted his penis like 2 inches into me, and only for a couple seconds. I had my period afterwards, but the day after my period, he fingered me and I had a light brownish / redish blood, that was left on only the fingers he inserted into me.

is this just regular spotting? or did he maybe "pop my cherry" or what is this?

I also just recently (about a month ago) started a new sport, so I have been somewhat stressed lately, any help would be GREATLY appreciated.

Thanks
