Am I Pregnant?

Heya! So my boyfriend and I last had sex while I was on my period. We used a condom, (and he pulled out for "extra safety") Afterwards, I got a UTI. (Common for me) It didn't last long, only a few days. A little while after the UTI had passed, I wiped after I went pee and there was a very small amount of blood. Last time I had a UTI, there was some bleeding, and it went away as the UTI healed. Could this bleeding just been from the UTI, or could it mean I'm possibly pregnant? (Ive had no other symptoms)
