Am I pregnant?

Okay so me and my boyfriend are trying to get pregnant so we have been having a lot of sex lately. I’ve recently had my period on the 17th of August. And just yesterday I noticed during sex that I was bleeding but the blood was brown. And I though it’s just cause it was rough. But this morning I noticed that I was spotting a brown colored blood again? I’ve already had my period so I know it can’t be that. Could it be that I’m pregnant???
