Taking the emergency contraceptive pill (levonorgestrel, like the i-pill) within five hours of unprotected sex is highly effective. However, no method is 100% effective. Additionally, the hormones in the pill frequently cause temporary cycle disruptions, which can delay your period by a few days or even a week. To give you peace of mind, the best next step is to take a home pregnancy test. This is highly accurate if done a week after your missed period. If you experience severe abdominal pain or your period is delayed by more than a week, please consult a doctor.

It is very common for your period to be late after taking the i-pill (emergency contraception), as its hormones can temporarily alter your cycle. Since your home test was negative, that is very reassuring. However, to be completely sure, I recommend repeating the home pregnancy test in one week if your period still hasn't started. If it remains negative and your period is still delayed, please consult a healthcare professional for a blood test or further evaluation. Try not to worry, as anxiety itself can also delay your cycle.

Taking the i-Pill within 24 hours of unprotected intercourse is generally effective, as it mainly works by delaying or preventing ovulation. However, no emergency contraceptive is 100 per cent reliable, and its effectiveness may be lower if ovulation has already occurred. Your next period may come earlier or later than usual, and temporary changes in bleeding pattern can occur. Monitor your cycle, and if your period is delayed by more than one week, take a home pregnancy test or consult a gynaecologist for further evaluation and guidance.

If the condom was used correctly and did not break or slip, it already provides strong protection against pregnancy, even during fertile days, so taking an I pill is not necessary, as emergency contraception is meant for situations where protection fails or sex is unprotected, and using it unnecessarily only exposes you to extra hormones without added benefit, so based on what you described, the risk of pregnancy is very low. However, if you still feel anxious, you can consult a gynaecologist for reassurance.

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 highly unlikely that your girlfriend is pregnant. The heavy five-day bleeding she experienced ten days after taking the I-pill (levonorgestrel) was likely a withdrawal bleed, indicating the pill worked. Because you have had no sexual activity since then, there is no new risk of pregnancy. Emergency contraception contains hormones that frequently disrupt menstrual cycles, which easily explains why her period is late and lighter this month. To ease your minds, she can take a home pregnancy test, which will be highly accurate by now.
