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.

i-pill should be taken after unprotected intercourse, not before. It is most effective when taken as soon as possible, ideally within 24 hours, and can still work up to 72 hours after sex. i-pill is an emergency contraceptive and should not be used as a regular method of birth control. If you find yourself needing it repeatedly or are unsure about contraception, it is best to consult a doctor for safer and more reliable long-term options.

Taking an emergency contraceptive pill when you are unsure about pregnancy is generally safe, but it can cause temporary side effects like nausea, headache, dizziness, breast tenderness, or changes in your next period (early, late, heavier, or lighter). If your period is delayed by more than a week, take a pregnancy test and consult a doctor.

Duoluton L Tablet is a combined oral contraceptive that is effective only when taken regularly. Irregular use reduces its reliability in preventing pregnancy. Since you had unprotected sex while taking the tablets irregularly, it is appropriate and safe to take an emergency contraceptive pill as soon as possible. Afterwards, continue your regular contraceptive regimen and consult a healthcare professional for guidance to ensure proper use and effective contraception.
