I was on my period and still bleeding and had unprotected sex.. I took a plan b two days after. Is there any way the pill wouldn’t have worked?

In brief: About Plan B...

Plan B 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. Yes, emergency contraceptive pills work most of the time, not all of the time.
