Bleeding(rough sex) or Spotting(symptom for pregnancy)

Yesterday, I had sex with my fb. And it was twice. The first was nice, we did it doggy style(and he came at my back). Then decided to do another one, but this time it was a sitting position—I turned my back on him. After a few minutes of grinding I saw myself bleeding, we didn’t finish it.

And according to this app, my period is approaching on March 28. Yesterday was 25th.

What was that bleeding all about?

But to be honest, the second attempt was kind of rough for me. It hurts.

Also, I want y’all to know that we had sex on March 11(about 4-5 minutes). It was 3 days prior to my ovulation day, said the app. We didn’t use any condoms, because we didn’t finish it. It was all pre cum.

Is it bleeding because of rough sex? Or spotting because of pregnancy?

I NEED HELP, ASAP!😭
