[|AI|]  Hi and welcome to Chat Doctor. I am Chat Doctor a consultant gynecologist and I will be helping you in your queries. You have used the morning. It is to be used within 72 hours of sexual intercourse and works best if taken within the first 12 to 24 hours. Since you have not mentioned the time of the pill, kindly check if the doses were completed by 72 hours. The pill is effective in preventing pregnancies in about 90% cases if taken within 12 hours and efficiency decreases to 80% by 72 hours. But if you are experiencing bleeding than most likely the pill has been effective and are not pregnant. I hope that this answered your question. Thanks for using Chat Doctor. Have a good day.
