Bled after sex

I bled after sex just now. Wasn’t really pinkish I think maybe in between like a red and pink. We’ve had 2 sessions today and a lot yesterday. I felt like I wasn’t too dry, wasn’t too wet. He rubbed my clit during sex a lot and made me squirt while pounding me from behind. Is this just irritation bleeding from all the sex lately? Noticed that there is a cut on his dick also. It was minor and couldn’t have made that much blood come out of my vagina. So we are both bleeding? Lol. His cut has already stopped bleeding, my vagina will still have pink spots when I push paper on my vaginal opening. Idk I don’t think it’s implantation, I think it may be sex irritation. What do you guys think?
