No medicine can prevent pregnancy 15 days after sex. Emergency contraceptive pills work only within 3–5 days of unprotected sex, so they are not effective at this stage. The next step is to wait for your period and, if it is delayed, take a pregnancy test (usually reliable about 3 weeks after sex or after a missed period). If you are worried, please consult a gynaecologist; they can guide you on safe options and provide support. Do not try to self‑medicate, as it will not prevent pregnancy now and may cause harm.

Since you are unsure whether intercourse was completed, there is still a chance of pregnancy. You can take the i-Pill emergency contraceptive tablet as a precaution. It is most effective when taken as soon as possible, ideally within 24 hours, but can be used up to 72 hours after the event. Take one tablet with water immediately, and be aware you may experience mild side effects like nausea, abdominal discomfort, or changes in your next period. If your period is delayed by more than a week, take a pregnancy test, and consult a doctor if you have any medical conditions or take other medications.

The i-Pill (levonorgestrel) is an emergency contraceptive medicine and works only when taken shortly after unprotected intercourse, ideally within 72 hours. It will not be effective for intercourse that happened several weeks ago, and it cannot start a period or end an existing pregnancy. Since your last period began on 4 April and you have not had your next period by 12 May, pregnancy is a possibility, even though intercourse happened on the last day of your period. The most appropriate step now is to take a home urine pregnancy test, preferably using the first morning urine for better accuracy. If the result is positive, you should consult a doctor for further advice and care. If it is negative but your period still does not come within a week, repeat the test and seek medical review. Stress, hormonal changes, or illness can also delay periods.

If your pregnancy is confirmed and you wish to terminate it, the safest approach is to consult a doctor or gynaecologist promptly. Early pregnancy (up to 10-11 weeks) can often be terminated safely and effectively using abortion pills (such as mifepristone and misoprostol), while later stages may require a minor surgical procedure. Do not take any medication to terminate the pregnancy on your own, as this can be dangerous and cause serious complications. Your doctor will guide you on the safest option based on your gestational age and health.

The I pill works best within 72 hours of unprotected sex. Still, since you may be ovulating now, its effectiveness is lower because it mainly works by delaying ovulation, so taking it now may still offer some protection, but the chance of pregnancy is higher. It is best to consult a gynaecologist immediately to discuss other emergency options, as individual responses can vary based on different factors.

Taking an i-Pill tablet (emergency contraceptive pill) a day before ovulation (release of a mature egg) reduces the risk of pregnancy, but it is not completely reliable, so a small chance may still remain. It mainly works by delaying ovulation, and its effectiveness may be reduced if ovulation has already begun. You should take a pregnancy test about 21 days after intercourse or wait until your period is more than 7 days late for accurate results. If your period becomes irregular or you notice unusual symptoms, consult a doctor for further evaluation and guidance.
