unexpected bleeding after sex?

tonight I got a little frisky during sex and he penetrated me pretty deeply, it was hurting but not that bad that I would’ve said to stop. we used a couple different and new things tonight that did hurt, some was like a pleasure pain. after all of that I noticed some blood on my shorts when I was about to get into the shower and every time I wipe myself I find more blood. it’s not heavy but it’s definitely there. my period was 2 weeks ago so it’s not that for sure.
