Can I just check, I had taken the 1st pill of Postinor 2 on the 17th day of my menstration cycle (within 24hrs of unprotected sex) and the 2nd pill 12 hrs later. I had unprotected sex again one day later. I did not take another set of postinor 2 pills as I had just took less than 2 days ago. What is the percentage of getting pregnant now?
