Hi welcome to the health care magic and thanks for asking your query here As you have taken postinor pill within timeline after unprotected sex there is little or no chances of pregnancy as the success rate of these emergency contraceptive pills are very high However i would strongly suggest you to visit your gynecologist If -your next period is more than 5 days late, or unusually heavy or light. • If you are still worried that you are pregnant. • If you have sudden or unusual pain in the lower abdomen and your period is late. • If you have any concerns about your health or about the methods of contraception that is most suitable for you. I hope it help thanks and get well soon
