Yes, emergency contraception (such as levonorgestrel) commonly causes a delayed period?often by a few days to a week?as it temporarily alters the hormone cycle. However, emergency contraception only protects against intercourse that happened *before* taking it; it does not prevent pregnancy from subsequent unprotected sex. Because of this, there is still a pregnancy risk. Please reassure her that a delay is normal, but taking a home pregnancy test about three weeks after the intercourse (or if her period is more than a week late) is the best way to be sure.

Using the i-pill (levonorgestrel) will not cause long-term fertility problems. However, because it contains a high hormone dose, using it monthly can disrupt your menstrual cycle and is less effective than regular contraception. For safer, ongoing protection, I recommend discussing regular options with your doctor. Great alternatives include daily oral contraceptive pills, barrier methods like condoms, or long-acting options like an intrauterine device (IUD). These are much gentler on your body and highly effective. Your fertility will return to normal as soon as you stop using them.

Since you took the i-pill (levonorgestrel) within three hours of intercourse, its effectiveness is very high. The bleeding you experienced the next day and the current brown spotting are common side effects of the high hormone dose in emergency contraception, which temporarily alters your menstrual cycle. While the chances of pregnancy are very low, the most reliable way to be sure is to take a home pregnancy test if your next expected period is delayed by more than a week.

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.

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.

Taking emergency contraception within 48 hours is still highly effective at preventing pregnancy. The light bleeding you experienced about a week later is a very common and expected side effect of the hormones in the medication, rather than a sign of pregnancy. While the likelihood of pregnancy is low, the most reliable way to be absolutely sure is to take a home pregnancy test 21 days after the unprotected intercourse.
