Hi there- i need to take 'ellaone' the morning after pill, but i also want to take norethisterone on friday as i go on holiday. can i do this?

I'd wait ...: Ellaone (ulipristal acetate) is a progesterone receptor modulator and norethisterone is a progesterone. Very possibly the effects of Ellaone may still be present, and impact the effectiveness of the norethisterone preventing it from stopping your period, or contributing to side effects such as nausea, etc. I think you need to pick using either one or the other to prevent hormone confusion!

YES.: Taking progesterone only to induce a period a few days after using the morning after pill shouldn't be harmful or reduce the effectiveness of either. Progesterone only pills can be used as a "morning after pill" but, since I don't know the strength of your norethisterone I can't instruct you on its use. Sounds like you may need to rethink the effectiveness of the contraception you normally use.
