The i-pill (levonorgestrel) is most effective when taken within 72 hours of unprotected sex. Its ability to prevent pregnancy decreases significantly after this timeframe, making it much less reliable after 72 hours. Since you are past this window, I gently encourage you to consult a healthcare provider or gynecologist as soon as possible. They can guide you on highly effective alternatives, such as a copper intrauterine device (IUD), which can prevent pregnancy if inserted up to 5 days after unprotected sex.

It is very common to experience changes in your menstrual cycle after taking emergency contraception. The hormones in these medications often cause irregular bleeding, spotting, or dark brown discharge instead of your usual period. Since you used protection and took the emergency contraception the very next day, the risk of pregnancy is very low. However, to give you complete peace of mind, I highly recommend taking a home pregnancy test. Since it has been over three weeks since intercourse, a test now will be highly accurate. Please consult a doctor if you experience severe abdominal pain.

Yes, taking the i-pill (levonorgestrel) 12 hours after unprotected sex is highly effective at preventing pregnancy. Emergency contraceptive pills work best the sooner they are taken, ideally within 72 hours. Since you are taking it so early, its effectiveness is very high. You might experience some mild side effects like nausea or slight changes in your next period, which is completely normal.

Having no penetrative intercourse, taking the emergency contraceptive i-pill (levonorgestrel), experiencing regular periods, and having multiple negative pregnancy tests since May make pregnancy virtually impossible. Your current symptoms of mild nausea, lower back pain, and stomach cramping are much more likely related to your history of PCOS or kidney stones. I gently recommend consulting your doctor to evaluate if a kidney stone or PCOS is causing this discomfort.

Yes, taking the i-pill (levonorgestrel) can indeed cause changes to your menstrual cycle, including heavier bleeding and abdominal pain. Because it delivers a high dose of hormones, these side effects are relatively common as your body adjusts. To help manage the discomfort, you can try using a warm compress or taking mild pain relief. However, if your pain becomes extremely severe, or if you are soaking through more than two pads an hour, please consult a healthcare professional to ensure your safety.

The i-pill (emergency contraception) contains hormones that can significantly delay your cycle. Since your pregnancy test is negative, this delay is likely due to the i-pill. However, please do not start Primolut (norethisterone) on your own. It is a hormonal medication that should only be taken under medical supervision to avoid further disrupting your cycle. I highly recommend consulting a gynecologist who can safely evaluate your health and advise if Primolut is right for you.
