Yes, your partner can still take emergency contraception. While levonorgestrel is most effective when taken within 72 hours, its effectiveness decreases after that. However, another option called ulipristal acetate remains highly effective for up to 120 hours (5 days) after unprotected sex. Alternatively, a doctor can insert a copper intrauterine device (IUD) within 5 days, which is the most effective emergency option. I gently encourage you to visit a local clinic or speak with a pharmacist as soon as possible to find the best choice for her.

No medicine can prevent pregnancy 15 days after sex. Emergency contraceptive pills work only within 3–5 days of unprotected sex, so they are not effective at this stage. The next step is to wait for your period and, if it is delayed, take a pregnancy test (usually reliable about 3 weeks after sex or after a missed period). If you are worried, please consult a gynaecologist; they can guide you on safe options and provide support. Do not try to self‑medicate, as it will not prevent pregnancy now and may cause harm.

Your missed period is likely a common side effect of the emergency contraceptive pill (i-pill) you took, though taking a pregnancy test is a wise first step. The itching, white discharge, and burning after sex could be a yeast infection, which frequently occurs after using antibiotics like metronidazole. It could also point to another infection. Since you recently restarted metronidazole, please consult your doctor. They can easily test you to find the exact cause, rule out conditions like pelvic inflammatory disease, and guide your treatment safely.

It is very common and completely normal to experience a delayed period after taking the i-pill (levonorgestrel). This emergency contraceptive contains hormones that temporarily disrupt your natural cycle, which frequently causes your period to be late, early, or different in flow. Since you took a pregnancy test five weeks after intercourse and it was negative, you can rest assured that you are not pregnant, as tests are highly accurate at this stage. Sometimes, the stress of worrying about a late period can delay it even further.

Yes, you should continue taking your daily birth control pills as scheduled, even if your period starts. Consistent daily use is key to building future protection. Please note that starting regular birth control pills 28 hours after sex does not act as emergency contraception for that specific event, so taking a pregnancy test in three weeks is a wise precaution. As your body adjusts to the daily hormone routine, you might experience mild, temporary side effects like nausea, breast tenderness, headaches, or light spotting. These are very common and usually improve within a few months.

It is very common to experience menstrual irregularities after taking an emergency contraceptive pill like the I-pill (levonorgestrel). This high dose of hormones can disrupt her cycle, leading to missed periods or unusual spotting for a cycle or two. Since her pregnancy test is negative, this light spotting is much more likely a side effect of the medication rather than implantation bleeding. Please reassure your sister that this is a typical reaction. If she took the pregnancy test at least three weeks after unprotected intercourse, the result is highly reliable. However, if she misses another period or experiences any pain, consulting a doctor would be a wise next step for her peace of mind.
