Bleeding!?

So me and my boyfriend had sex last night. We usually go 2-3 days without having sex and then of course have sex lol. He’s rather on the bigger side, at least too me he is lol. But I woke up this morning and I went pee, and there was blood when I wiped. It was light pink, and i didn’t bleed on my underwear or Anything. And I’m 8 days DPO.

I’m also not supposed to get my period till like 2-3 weeks from now.

So idk maybe if the sex was to rough or could this possibly be something else I should be worried bout?

Has anyone had this happen, if so, what was it ?
