Thread: Took plan B and now my period is lasting 3 weeks!

After having sex with my boyfriend, we realized the condom broke. I had been off of birth control for about 3 weeks so we rushed to the pharmacy to pick up plan B. I took the plan b one step pill within 45 minutes of ejaculation. 8 days later, I got what I assumed to be my period. It was really light and brownish in color, almost like the last day of your period. This lasted for a full week, and on the last day (a sunday) I began taking my regular birth control pill (ortho tri cyclen lo). On monday morning I noticed that my period was back! But this time it was heavier than the week before and more red and clumpy. I had the worst cramps of my entire life on wednesday and thursday. I have continued to take my birth control on schedule but now I am going into the third week of having my period! What is going on with my body?? and how do i make my period stop?!

Hi Kate,

Because you don't include where you were in your mentral cycle in your above post, it is difficult to say what exactly is going on. If you were expecting your period 8 days after intercourse, then the chances are pretty slim that you would have gotten pregnant. I have been on ortho tri cyclen lo, and for me... it made me miss months of periods... so I would think if you had the same experience prior to this episode, that maybe being off of your pills for 4 weeks caused a period that was not regulated and supressed as you're used to with the pill?

Regardless a 3 week period is concerning, and I'm sure it's a major stressor to you. I would contact your doctor for advice. Good luck!
