Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... No chances of pregnancy are very less post intake of postinor 2, especially if it was taken within 24 hours of having sex. Actually postinor 2 is an emergency contraceptive pill which works by inhibiting implantation of fertilized egg on the uterus. It has high success rate of over 95% if taken within 24 hours of having sex. Therfore chances of pregnancy are very less despite you being ovulkating at that time. As you took the pill 5 hour later of having sex, You should now relax as pregnancy possibility is very less. You might have your next period delayed due to intake of postinor. Don t take postinor 2 or any morning after pill frequently. These pills are intended to use in case of emergency & have higher side effects than other regular methods of contraception such as regular birth control pill, condom etc. If your next period is delayed by more than 2 weeks you should undergo a pregnancy test to rule-out pregnancy possibility Refer to a gynaecologist for more queries Don t worry you would be fine Hope this information helps
