[|Human|] Hi, I had unprotected sex on 22 of February, seven days before my period was due. I took an emergency contraceptive within 4 hours and 7 days later I got my period on time. It lasted about 4 days starting with heavy bleeding and an abrupt decrease after two days. I am currently waiting for my next period and want to know what the chances of being pregnant at this stage are?
[|AI|]  Hi. Thanks for consulting us. If you have not had any unprotected intercourse during this cycle then pregnancy is extremely unlikely at this stage. Emergency contraception if taken within 72 hours of sex can prevent 86% of expected pregnancies & you had a period after that. So, this is a new cycle. Don't worry & think about using a regular birth control method to avoid such anxieties in the future. Regards.
