This emergency contraceptive contains hormones that can temporarily alter your wife's menstrual cycle, causing her period to be lighter, heavier, early, or delayed. While spotting is typical, we cannot completely rule out pregnancy based on symptoms alone. To give you both peace of mind, I recommend she take a home pregnancy test if her expected period is delayed by more than a week, or three weeks after taking the pill.

Taking the i-pill (an emergency contraceptive) can temporarily disrupt your hormone levels. Crina NCR (norethisterone) is a hormone medication, and your period (withdrawal bleed) should typically start within 3 to 10 days after you finish the prescribed course. No additional medication is needed to bring on your period right now. Please complete your current course of Crina NCR as directed by your doctor. If your period does not start within 10 days of finishing the medication, a quick check-in with your gynecologist will help put your mind at ease.

It is highly unlikely that your girlfriend is pregnant. The heavy five-day bleeding she experienced ten days after taking the I-pill (levonorgestrel) was likely a withdrawal bleed, indicating the pill worked. Because you have had no sexual activity since then, there is no new risk of pregnancy. Emergency contraception contains hormones that frequently disrupt menstrual cycles, which easily explains why her period is late and lighter this month. To ease your minds, she can take a home pregnancy test, which will be highly accurate by now.

Taking the i-Pill (emergency contraceptive pill) within 2 hours of intercourse is very effective in reducing the risk of pregnancy. Given the timing, your bleeding is most likely a hormone-related withdrawal or breakthrough bleed caused by the i-Pill rather than a true period. Such tablets commonly cause early, delayed, lighter, or slightly irregular bleeding due to temporary hormonal changes. Implantation bleeding is uncommon and usually occurs about 6 to 12 days after ovulation (release of a mature egg), not immediately after taking emergency contraception. Your next period may still come earlier or later than expected, which is also normal after taking this medication. If your next period is delayed by more than a week, take a pregnancy test 3 weeks after the incident for reassurance.

i-pill should be taken after unprotected intercourse, not before. It is most effective when taken as soon as possible, ideally within 24 hours, and can still work up to 72 hours after sex. i-pill is an emergency contraceptive and should not be used as a regular method of birth control. If you find yourself needing it repeatedly or are unsure about contraception, it is best to consult a doctor for safer and more reliable long-term options.

Taking the i-pill (levonorgestrel) within 67 hours offers protection, though emergency contraception is most effective the earlier it is taken. A 7-to-8-day delay is a very common side effect of the hormone in the i-pill, but it could also suggest pregnancy. I recommend taking a home pregnancy test now. If it is negative, wait one week and test again if your period still hasn't started. For future planning, the fertile window is usually 12 to 16 days before your next period. Tracking your cycle helps, but regular birth control is always the safest approach.
