Emergency contraceptive pills (such as levonorgestrel) are highly effective, preventing about 75% to 95% of expected pregnancies when taken promptly. The most reliable sign that it worked is the arrival of your next monthly period, which might be slightly early or late due to the hormonal changes. The only definitive way to confirm you are not pregnant is to take a home pregnancy test 14 to 21 days after the intercourse.

Taking the emergency contraceptive pill (i-pill) on June 28, followed by withdrawal bleeding on July 9, indicates the medication was effective. The heavy bleeding starting on August 16 is consistent with a menstrual period, which further confirms she is not pregnant. Emergency contraceptives can temporarily disrupt hormone levels, causing changes in cycle timing and flow. To give you both complete peace of mind, she can take a simple home pregnancy test for a definitive answer. Please reassure her that everything appears to be on track, and consult a healthcare professional if she has any persistent concerns.

It is important to understand that an emergency contraceptive pill like the I-pill is not 100 per cent effective. Its effectiveness depends on timing; it works best when taken as soon as possible after unprotected intercourse. It is not meant to be a regular method of contraception, since your periods are already delayed there could be multiple reasons like hormonal imbalance, stress, pregnancy, or irregular cycles, so relying only on I pill for planned unprotected sex is not a safe or reliable option, it is strongly advised to consult a gynecologist to understand your cycle delay and to choose a proper regular contraception method like condoms or other reliable options to prevent unwanted pregnancy and reduce health risk.

The bleeding you experienced after taking the i-pill (levonorgestrel) is a common side effect and does not guarantee you are not pregnant. Both this emergency contraceptive pill and stress can definitely disrupt your hormone levels, which frequently causes your next period to be delayed. To help put your mind at ease, I recommend taking a home pregnancy test 21 days after the intercourse. Please try to rest and take deep breaths?your body is just adjusting to the hormonal shift and stress.

Apart from emergency contraceptive pills, there are several highly effective regular options available. These include: 1. Daily Oral Contraceptive Pills (containing hormones like estrogen and progestogen). 2. Barrier Methods (such as condoms, which also protect against STIs). 3. Long-Acting Reversible Contraception (LARC), including Intrauterine Devices (copper or hormonal IUDs) and hormonal implants placed under the skin. 4. Injectable Contraceptives given every few months. Regular methods are much more effective and safer for ongoing pregnancy prevention than emergency pills. Please consult a healthcare provider to choose the best option for your body.

it is very common for the i-pill (levonorgestrel) to temporarily disrupt your menstrual cycle, making your period early or a few days late. Because you took the emergency contraceptive five days ago, this delay is a normal side effect of the hormones. I recommend waiting a few more days to see if your bleeding starts. If your period is delayed by more than a week, or if it has been three weeks since the unprotected sex, taking a home pregnancy test will help give you peace of mind.
