The i-Pill (levonorgestrel) is an emergency contraception pill designed for use after unprotected sexual intercourse. Taking it 10 minutes before intercourse is not recommended and will not reliably prevent pregnancy. It mainly works by delaying or preventing ovulation (the release of a mature egg from the ovary). For this medicine to be effective, it should be taken after intercourse when there is a risk that sperm may already be inside the body. If it is taken before intercourse, its effect may not last long enough to protect against pregnancy, especially if ovulation happens later. Therefore, protection cannot be guaranteed. It should be used as soon as possible after unprotected sex, ideally within 24 hours and up to 72 hours. For regular protection, a routine contraceptive method, such as condoms or an intrauterine device, is more reliable. If you have any concerns, consult a doctor for personalised advice.

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.

Taking an emergency contraceptive pill like the i-pill (levonorgestrel) 48 hours after unprotected intercourse is still highly effective. While these pills work best within 24 hours, they still offer strong protection up to 72 hours. Because your subsequent sexual activity was protected, there is no added risk from those encounters. Overall, your risk of pregnancy is low. For your peace of mind, I suggest taking a home pregnancy test if your next period is delayed by more than a week.

Taking emergency contraception immediately after intercourse makes it highly effective, reducing your risk of pregnancy to about 1% to 2%. You've taken the right steps. For ongoing protection, contraceptive injections (using generic medroxyprogesterone acetate) are an excellent, highly reliable option. When received on schedule every three months, they are over 99% effective at preventing pregnancy without needing daily action or barriers. Please consult your healthcare provider to discuss if the injection is the right fit for your body.

Yes, there is a possibility she could be pregnant. While the i-pill (levonorgestrel) is highly effective, it is not 100% foolproof, especially if ovulation had already occurred. The bleeding she experienced on the same day was likely not a normal period, and her current symptoms?vomiting and a 50-day missed period?are common signs of pregnancy. Please advise her to take a home pregnancy test using her first morning urine as soon as possible. Regardless of the result, she should visit a gynecologist for a proper evaluation and guidance.

It is completely understandable to feel anxious about this. Taking the i-pill (levonorgestrel) can temporarily alter the menstrual cycle. Typically, it may cause the next period to be early, on time, or delayed by up to a week (7 days). If her period is delayed by more than 7 days, it is best to take a home pregnancy test to be sure. If you both have further concerns, consulting a doctor can offer peace of mind.
