On the 10th i got my period as normal then on the 13th my period was light as usual basically they was nuttin flowing then on the 13th my bf and i had sex(he ejactulated) i cleaned up with soap and then got PLAN B and HOur LAter. and followed up with the 2nd dose twelve hours later.

On the 15th i woke up with blood it was red and then after started to see brown discharge and its off and on and its been going on from the 15th to 16th... what is that brown discharge? am i preggo?

More than likely it is from the plan b....it is not uncommon to have some bleeding after using it as it is a high dose of hormones.

It is pretty effective at preventing pregnancy, but not 100%.....you'll have to wait until your next period is due, or if you wanted, you could try a pregnancy test in about 2 weeks. Odds of a pregnancy would be low since you took the plan b and you had just finished your period.

If you don't want to become pregnant, be sure to use protection everytime you engage in sex. Plan b is only for emergencies, so be sure you don't rely on that as your contraceptive method.
