How do I know it has worked?

You will know Levonelle One Step® has worked when you have your next period and it seems like a normal period.

If your period is more than 5 days late, or unusually heavy or light, or you are still worried, you should visit your doctor or family planning clinic for a check up to make sure you're not pregnant.

If you are very anxious about an unplanned pregnancy or any other aspect of having had unprotected sex, get in touch with your doctor or family planning clinic or go to Advice and Support now.
