Will Emergency Contraception Change My Period?

Emergency contraception shouldn't significantly change the timing of your period -- it may be on time, or come a few days early or late. Most women get their next period within seven days of the expected time. Make sure you use protection if you have sex while waiting for your period, or you could become pregnant.
When you do get your period, it could be heavier or lighter than normal. You might also notice some spotting in the days after taking EC.
Contact your healthcare provider if you have not had a period within three weeks of taking EC pills or if your period is over a week late. It is possible that you are pregnant (see When to Take a Pregnancy Test for more information).

Final Thoughts

If you have additional questions about what to expect from emergency contraception, talk to your healthcare provider or pharmacist. The types of things to expect will vary depending on which EC option you choose. In general, it is a good idea to make sure you have all your questions answered before using any emergency contraception medication.
