Hi,

Postinor 2: If taken within 24 hours, 95% chance of preventing pregnancy & within 72 hours it falls to 58% & after 72 hrs, results are not sure. Any contraceptive pills you take are not always 100% protective & also in your data you haven't mentioned the timings when you consumed it.

I advise you to do serum beta hCG test which is more reliable than HPT, if you didn't get your periods after 3 weeks of taking the pill. Also Consult a gynecologist for further assistance.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Yogapriya Vasudevan, General & Family Physician
