It is highly likely that the nausea you are experiencing is a common side effect of the emergency contraceptive pill (such as the i-pill, which contains levonorgestrel). These pills contain a high dose of hormones that frequently cause mild stomach upset or nausea for a few days after taking them. Two days is far too early for pregnancy symptoms to appear, as those typically take at least two weeks to develop. If your nausea persists beyond a few days, or if your next period is delayed by more than a week, taking a simple home pregnancy test then will help give you peace of mind.

Emergency contraception pills (such as levonorgestrel) only protect against pregnancy from intercourse that occurred before taking the medication. They do not prevent pregnancy from subsequent unprotected intercourse, even the very next day. If subsequent unprotected intercourse occurred, another dose may be needed to ensure protection, depending on the type of pill taken. I highly recommend speaking with a pharmacist or healthcare provider as soon as possible to guide you and your partner on the safest next steps.

A positive home test usually indicates pregnancy, as emergency contraceptive pills like the i-pill are highly effective but not 100% guaranteed. Your history of PCOS can cause irregular periods, but it does not cause a false positive pregnancy test. Please be reassured that you have time and safe options. Your first step should be visiting a healthcare provider for a blood test and an ultrasound to confirm the pregnancy and determine how far along you are. From there, your doctor can guide you through all your options, whether you choose to continue the pregnancy or explore safe termination.

The i-pill is an emergency contraceptive designed to work temporarily by delaying ovulation to prevent pregnancy in the short term. Its active ingredients leave your body quickly, typically within a few days, and it has no long-term impact on your fertility. If you have been trying to conceive and are experiencing difficulties, there may be other factors to consider. I highly recommend consulting an obstetrician-gynecologist for personalized support.

Emergency contraception, such as levonorgestrel, is highly effective, and the light bleeding you experienced a week later is a very common side effect indicating the hormones are working. These hormones frequently disrupt your natural cycle, which easily explains your currently missed period. Since you have not had further intercourse, pregnancy is unlikely. However, to give yourself complete peace of mind, I recommend taking a simple home pregnancy test, which will be highly accurate by now.

Yes, it is safe and necessary to take a second dose of emergency contraception like the iPill (levonorgestrel) if you have another episode of unprotected intercourse. The first dose only protects you from intercourse that occurred before taking it; it does not provide ongoing protection. While safe, a repeat dose might cause temporary side effects like nausea or an irregular next period. For reliable, ongoing protection, I gently encourage you to discuss regular birth control options with your healthcare provider when you can.
