How do I know if it worked?

How effective is taking the ellaOne® morning after pill?

If you need to take the ellaOne® morning after pill, you must take it as soon as possible and within five days of having unprotected sex. You will know 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.

Taking a pregnancy test

If you have had unprotected sex, take a pregnancy test if you experience any of the following:

  • Your period is more than 7 days late
  • Your period is unusually light or unusually heavy
  • You have symptoms such as abdominal pain, nausea, vomiting or breast pain
  • You have any doubt about being pregnant, do a pregnancy test

Pregnancy tests can be purchased at your local pharmacy, just like ellaOne®.
