Raw Sex? Possibly pregnant? idk help!!

I was giving my boyfriend oral sex and he asked to stick it in and I stupidly said yes and we had sex for exactly a min before I told him it was not safe and we stoped (he didn't cum) and then one week late we had Sex again (with a condom) and he stoped and jacked off and came on my titties. Today ( 2days later) from having sex with a condom there was  a red and brown discharge in my undies what does this mean? Please helppppp
