If you wish to start a regular method of contraception after using ellaOne®, you can do so but you should also use condoms until your next period.  ellaOne® may make regular hormonal contraceptives, like  pills and patches, temporarily less effective. If you are currently taking hormonal contraception, continue to use it as usual after taking ellaOne®, but be sure to use condoms every time you have sex until your next period.

How do I know if it worked?

You will know that ellaOne® has worked when your next period starts. After taking ellaOne®, most women have a normal period at the expected time. But some may have their period later or earlier than normal.1

If your period is more than 7 days late, or is unusually light or unusually heavy, or if you experience symptoms such as abdominal pain, nausea, vomiting or breast pain, or if you have any doubt about being pregnant, do a pregnancy test.1
