It’s not officially licensed for this use, but you can delay your period using Evelyn. You should let us know first though, as Evelyn isn’t primarily prescribed for this.
To delay your period, once you’ve finished your yellow active pills, move straight on to a new strip, rather than taking the 7 inactive pills. You may get some light or menstruation-like bleeding while using the second strip. Once you’ve finished the second set of active pills, take the 7 white inactive pills, and then start the next strip.
