Might I be pregnant?

Silly question here, but I need answers.

So, I had sex, protected sex, two days after my ovulation stopped. I was a bit paranoid that I would miss my period because (I am very anxiety prone) there was a brief time where the guy tried to raw me, but I stopped him. Also, after he came, he did it on top of my vagina (which I didn’t appreciate) BUT, I know it’s not likely to get pregnant that way...

Anyway, I got my period a week later (yay!) but now it’s over with. This morning (a day later) I wiped and had light red almost pink blood on my tissue after wiping. I heard that pink blood indicates early pregnancy signs. Might I be pregnant? Or is it just left over blood trying to clear out my system?
