I had sex on the 4th day of my period. (still bleeding) it was unprotected but he pulled out. took map 12 hours later. should we be okay?

About Plan B...: Plan B (or other "morning-after" pills) can alter the menstrual-type bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time. "Should we be ok?" means different things to different people.
