Brown discharge after taking Plan B, after unprotected sex (didn't ejaculate)

[sidsyed]

My girlfriend and I had sex on the 17th of March at around 11:00PM. I was unprotected (no condom), but I pulled out. To be safe, we decided to take Plan B (1.5mg, up to 72 hours). She took it the next morning at around 8:00AM (9 hours after sex). Her last period was 5th-11th March, and her next period should be 8th-13th March, but she got brown discharge for the past few days.

Is she pregnant?

Spotting after taking plan B is common.  Plan B is a big dose of hormones and this messes up a woman's system a bit.  They are often irregular for 2 to 3 months after taking it. Be sure to use good protection until she is regular again because you don't know when she'll next ovulate.  good luck
