Two months ago, i took a plan b pill. i have had a period for over a week now, and it has been unusually light, now i'm getting a brown discharge.

Normal: After taking the Plan B pill you can have irregular menstrual cycle. The pill has a large amount of estrogen to discourage a healthy environment for embryo to grow. In the next month you should have a normal period. The menstrual blood can be brown at the beginning or end of your cycle and this is normal as well. Take a pregnancy test to make sure you are not pregnant and follow up with a PCP
