Bleeding after sex?

I’ve been sexually active for about half a year now, with only one guy. Today, for the first time ever, I noticed I bleed after having had sex. (not on my period atm haha) I didn’t not bleed after our first time, which I know sometimes happens cuz of the hymen and everything. Is this something to be concerned about? Is this perhaps my hyman tearing or just a sign of rough sex? I know if it keeps happening it is probably a bigger issue
