Hello,

If it is still within 72 hours of sex, taking an i-Pill is recommended to reduce pregnancy risk. Regesterone (norethisterone) is mainly prescribed for delaying periods. It is not a contraceptive pill. Continue to take Regesterone as prescribed by your doctor, but expect period changes like irregular bleeding, a delayed next period, and spotting. If your period is delayed by more than a week after stopping Regesterone, do a pregnancy test.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Nupur K., General & Family Physician
