A four-day delay in your period is a very common side effect of the i-pill (levonorgestrel), as it temporarily alters your hormone levels. While there is still a small chance of pregnancy, a delay is expected. Most importantly, if you do happen to be pregnant, medical evidence shows that the high dose of hormones in the emergency contraceptive will not harm your baby or affect the pregnancy. To give yourself peace of mind, I recommend taking a simple home pregnancy test.

Since your period is expected today, your risk of pregnancy is quite low, as ovulation likely occurred about two weeks ago. However, the withdrawal method is not completely reliable, and residual sperm from earlier masturbation can sometimes be present. If you want maximum peace of mind, taking emergency contraception, such as levonorgestrel or ulipristal acetate, is a safe and reasonable option. Levonorgestrel is available over-the-counter and is most effective when taken within 72 hours.

Please rest assured that emergency contraception, like the i-pill (levonorgestrel), does not cause long-term menstrual irregularities. While it commonly disrupts your very next cycle?causing temporary delays or changes in flow?its effects wear off quickly. A missed period or persistent irregularities several months after taking it are highly unlikely to be related to the pill. Other factors, such as stress, weight changes, hormonal fluctuations, or a new pregnancy, are more likely causes. I gently encourage you to consult a healthcare provider or gynecologist for a simple evaluation to help bring you peace of mind.

It is very common to experience a delayed period after taking emergency contraception, such as levonorgestrel. These hormonal medications frequently cause temporary changes in your menstrual cycle, which can lead to early spotting (the brief bleeding you noticed) and delay your expected period by several days. A three-day delay is quite normal in this situation. However, for peace of mind and to be absolutely sure, I recommend taking a home pregnancy test if your period is delayed by more than seven days.

While a negative blood test is highly reliable, taking multiple 'I-pills' (levonorgestrel) can significantly disrupt your menstrual cycle, making your expected period date hard to predict. To be absolutely sure, I recommend taking another pregnancy test 21 days after your last unprotected intercourse. This timeframe will give you the most accurate and definitive result.

The I-pill (levonorgestrel) can significantly delay a period, which is a very common side effect. However, emergency contraception does not protect against unprotected sex occurring after taking it. Since the pregnancy tests showed no lines at all?not even the control line?the tests are likely invalid. I recommend taking a new pregnancy test, following the package instructions carefully, or visiting a doctor for a reliable blood test. There is a chance of pregnancy from the second encounter, but a valid test will give you clear answers.
