... day i was fertile and me being a worry person about getting pregnant (im a virgin, unless putting the very tip in me counts) took Plan B one step (for the first time). After two days i bled a drop or two of brown blood, which looks like old blood, and about 7 days counting the incident with the first time spotting.. I started to get really bad cramps which then lead to bleeding or "spotting" (since it wasnt as much to fill up a tampon). I have 13 days left till I should be getting my real period. Is this normal?
I never took birth control before either.

Help
