Took plan b pill right before my period was due. period is late, cramps, and brown discharge. pregnancy test negative. am i pregnant?

Not likely . . .: If your pregnancy test is negative and you had your regular period, it's very unlikely that you're pregnant, especially if you took plan b. But rather than undergo that emotional stress again, talk to your family doc about some form of contraception. And make him wear a condom anyways to prevent sexually transmitted disease/infection.
