Question: how long does it take for your period to come after taking norethisterone?
Answer: You'll usually be prescribed 3 norethisterone tablets a day, starting 3 to 4 days before you expect your period to begin. Your period should arrive 2 to 3 days after you stop taking the medication. But norethisterone does not act as a contraceptive when used in this way, so you could still get pregnant.
