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.

Within 72 hours: You must use ir within 72 hours of the episode of unprotected intercourse. Even then it is only 75% effective so you must take a pregnancy test if you are late with your period.

Preg test: After you take emergency contraception you should expect to see a period within a few days to a week. If not you should check a pregnancy test to make sure that you are not pregnant.
