If plan b is supposed to delay ovulation why do i feel like im ovulating? i took the pill on tuesday 6 days before my ovulation date and wanted to be sure if this was normal?

Plan B should work: Plan B works very well when taken the day of sex or the day after sex. However, very well is not perfect (and nothing in this world is perfect), so there is a small chance of pregnancy. Plan B can alter one's menstrual bleeding for 1-2 cycles, so a late period won't necessarily mean a pregnancy. One should do a home pregnancy test 3 weeks after sex, to see if there is a pregnancy.
