Is it normal to have a 2-4 day period after taking Plan B?

One of the most common side effects of taking Plan B (or emergency contraception) is some sort of bleeding. Because Plan B contains such a large dose of hormones, a certain amount of bleeding is expected. For some people, they might have a full period, light spotting, or anything in between.

While this can be normal, call your doctor to find out for sure. They will be able to answer any questions you may have about the medication.
