Pregnancy scare

I had sex with my boyfriend 11 days ago, 4 days ago, and 3 days ago. I'm not sure that all of those days matter, but I would rather spill all the details and get a better response than excluding information. For the past day I have been seeing a small amount of blood when I pee. It's not like period blood, but it shows up on my toilet paper when I wipe. Could this be a sign of pregnancy? We always use a condom and he pulls out before he cums too. I know anytime you have sex there is a possibility for pregnancy , but Ive never bled before like this for no reason.
