I am a woman aged 27. Last Friday, I had unprotected sex with my partner and he didn’t withdraw. I took Postinor 2 after that but I missed the time for the second tablet. Will it reduce the effectiveness of the drug? What should I do as we don’t have any marriage plan yet?

Hello and good afternoon.

Thank you for your question.

Based on your question, I understand that you are worried about your situation. I will try to help you.

For your information:

  • Postinor 2 can be taken at any time of your menstrual cycle, given that your period is not late.
  • Postinor 2 is an emergency contraceptive that can be used to prevent pregnancy when used within 72 hours after unprotected sex.
  • Postinor 2 can prevent up to 85% of pregnancies ( 95% of unwanted pregnancy if taken within the first 24 hours after unprotected sex and it decreases to 58% if taken between the 48 hours to 72 hours after unprotected sex. There are research incating that both doses can be taken at the same time. However, you may experience more side effects due to the high dose of hormone.
  • No known evidence of prevention of pregnancy by Postinor 2 when taken after 72 hours of unprotected sex.

However, to identify whether you are pregnant or not, you can do a pregnancy test at home or else go to a doctor at a nearby clinic or hospital.

Therefore I highly recommend you speak to your doctor regarding your situation to provide you with the safest and best route of care to manage your condition as a whole, taking into account the various factors mentioned above and more. You can contact our doctor online for further information and treatment.

I hope this answer helps you. Thank you.
