I've been on my period for two weeks. i took the plan b pill and got my peiord about 6 days after taking it. i'm still bleeding should i be concerned?

Plan B: You can expect unscheduled, irregular bleeding for days to weeks after using Plan B. Plan B is good at preventing pregnancy, but has bad bleeding side effects. Check a pregnancy test, then make an appointment to see a gynecologist (such as myself in West Jordan), as soon as possible to get a more tolerable long-term contraception plan.
