Two positive home pregnancy tests after a missed period strongly suggest pregnancy, even though you took the i‑pill within 18 hours after sex. The i‑pill reduces the chance of pregnancy but is not 100% effective. Sometimes it can delay periods, but repeated positive results should not be ignored. You should see a gynaecologist soon for confirmation with a blood beta‑hCG test and an ultrasound to check the pregnancy’s location and duration, and to discuss further options safely. Do not take any more emergency pills or medicines on your own. If you develop severe abdominal pain, heavy bleeding, dizziness, or fainting, seek urgent medical care, as these can rarely indicate an ectopic pregnancy.

Yes, emergency contraceptive pills like the i-pill (which contains levonorgestrel) are highly effective at preventing pregnancy. For the best results, the pill should be taken as soon as possible, ideally within 72 hours (3 days) of unprotected intercourse. While it can still be taken up to 120 hours (5 days) later, its effectiveness decreases over time. It is generally very safe, though she might experience mild, temporary side effects like nausea or a slightly altered next period. If her period is delayed by more than a week, a simple pregnancy test is recommended.

It is very common and completely normal to experience a delayed period after taking emergency contraception like the i-pill (levonorgestrel). Because these pills contain hormones to prevent pregnancy, they can temporarily throw off your natural cycle, causing your period to be early, late, or lighter/heavier than usual. Try not to worry, as this is a frequent side effect. To ease your mind and rule out pregnancy, the best next step is to take a home pregnancy test. For the most accurate result, wait until your period is at least one week late, or three weeks after you took the pill. If you have any concerns, your doctor is always there to help.

Experiencing a normal three-day bleed is a very positive sign and means pregnancy is highly unlikely. The i-pill (levonorgestrel) you took is effective when taken within 72 hours, though its hormones can sometimes alter your bleeding cycle. While this bleeding is very reassuring, the only way to be absolutely certain is to take a home pregnancy test 21 days after the unprotected intercourse.

Emergency contraceptive pills (like the i-pill) only work when taken after unprotected sex. They prevent pregnancy by delaying ovulation. Taking the pill before sex, even a day earlier, is not effective because its effect is short-lived and depends on your menstrual cycle. To work, the pill must be taken after the unprotected event, ideally within 72 hours.

Delayed period after taking the i-pill (levonorgestrel) is quite common. This emergency contraceptive contains hormones that can temporarily upset her natural cycle. Since she has already had a negative pregnancy test, that is a very reassuring sign. However, because the delay has exceeded 15 days, I recommend taking one more home pregnancy test now to be absolutely sure, as it will be highly accurate by this point. If it is still negative and her period does not arrive within a week, a gentle consultation with a doctor can help provide further peace of mind.
