A delayed period is a very common side effect of the i-pill (levonorgestrel). The hormones in the medication can temporarily disrupt your cycle, making your period a few days early or up to a week late. Since you took it within 24 hours, its effectiveness is very high. To give you peace of mind, the best time to take a home pregnancy test is 14 to 21 days after the intercourse, or if your period is more than a week late. If your period is delayed by more than two weeks, please consult a healthcare professional.

The i‑pill (levonorgestrel emergency contraceptive) may not provide protection for intercourse that occurs after it is taken. Since you had unprotected sex again 24 hours later, it is recommended to take another i‑pill as soon as possible (ideally within 72 hours) to reduce the risk of pregnancy. Emergency pills are meant for occasional use, and repeated doses in a short time may increase side effects. For ongoing protection, it is safer to use a regular contraceptive method, such as condoms, daily oral contraceptive pills, or another method advised by your doctor. If you have any doubts or experience vomiting soon after taking the pill, consult a doctor or pharmacist for guidance.

Your symptoms could stem from a few related factors. Initial sexual intercourse can sometimes cause minor tissue micro-tears that need time to heal. Additionally, repeated use of emergency contraceptives (containing levonorgestrel) can temporarily alter your hormone levels and vaginal pH, making you more susceptible to yeast infections or bacterial vaginosis. Tight clothing traps moisture, further irritating the delicate skin. I highly recommend wearing loose cotton clothing and scheduling a gentle evaluation with a doctor to get you the right relief.

Emergency contraceptive pills (like levonorgestrel or ulipristal acetate) can sometimes fail if ovulation has already occurred before taking the pill, if there is a higher body mass index, or if vomiting occurred shortly after ingestion. If a pregnancy does occur, safe medical options are available. A medical abortion using a combination of mifepristone and misoprostol is highly effective in the early weeks of pregnancy. I warmly encourage consulting a healthcare provider or a family planning clinic.

It is highly unlikely your partner will get pregnant. You used protection, and she took the emergency contraceptive (I-pill, containing levonorgestrel), which provides very strong backup protection. Since she took two doses, she might experience temporary side effects like nausea, headache, or changes in her next menstrual cycle (it may be early, late, or spotty). For peace of mind, she can take a home pregnancy test if her period is delayed by more than a week.

Please rest assured that what you are experiencing is a very common side effect. The i-pill contains levonorgestrel, a hormone that prevents pregnancy by temporarily altering your natural hormone levels. This sudden hormonal shift frequently causes harmless breakthrough bleeding or spotting about a week after taking the pill. It is not a cause for alarm, and your next period may also be a few days early or late. However, if you experience extremely heavy bleeding, severe abdominal pain, or if your next period is delayed by more than a week, please take a pregnancy test or consult a doctor just to be safe.
