After taking emergency contraception (EC) like Plan B (AKA the morning-after pill), it's common to experience changes in your menstrual cycle. This can include changes in the timing and intensity of cramps. However, these changes will be different from person to person. 

Some people get cramps that last for a few days after taking Plan B, while others may not experience any cramps at all. If you're worried about how long your cramps are lasting after taking Plan B, you can contact your nurse or doctor, like the ones at your nearest Planned Parenthood health center. They can help you make sure everything is okay.
