So my boyfriend and I had sex but he wore a condom and comed In it and then whip his penis of and stuck it back in but he didn't come inside me. I was on my period like 2-3 into It and I took the plan b pill. Do I still have a chance of being pregnant?

Pregnancy unlikely. Pregnancy is unlikely because one was on her second or third day of her menstrual period and because she took Plan B after sex. However, the boyfriend can go to the store and buy a box of urine pregnancy tests. One can keep the tests and do one in 3 weeks to confirm non-pregnancy. Meanwhile, consider asking said boyfriend to stay away until non-pregnancy is confirmed (just as a friendly reminder).
