Bleeding after clitoris stimulation?

I masturbated with myself last night and this morning and I brought myself to an orgasm by rubbing my clit. But this morning my vagina started bleeding a little?? There's none last night and this is the first time I'm seeing this. It's day 13 of my cycle and I had unprotected sex on day 5 of my period but the guy did not ejaculate into me. I had sex on day 11 again but it's protected as we used a condom. What's wrong with me? There's no pain or whatsoever but my vagina just bled after I orgasmed this morning and I'm scared.
