I had unprotected with my bf 5-6 days before my period that was last year December and we weren't 100% sure so we got postinor 2, I got my period exactly the same date it was suppose to come after using the postinor 2 but the bleeding was just for a 2 day

Hello, Annynhhgv1234! Thank you for posting.

Firstly, to avoid this kind of situation in the future, always use protection.
Emergency contraceptives are up to 95% effective when taken as prescribed within the first 24 hours and up to 90% effective when taken within 72 hours. It works by preventing ovulation and stopping a pregnancy from starting. It will not end a pregnancy already in place. Side effects can include stomach aches, headaches, nausea and a general feeling of being unwell. The more frequently they are taken, the more likely a woman is to have side effects and an irregular cycle. They should be taken only for emergencies, not used as a regular method of birth control.

Symptoms usually start 2-7 days after taking the medication and may or may not include bleeding or spotting. If a woman doesn’t get her next period within a week of it’s expected a date, a pregnancy test is advised. Periods can often be delayed or longer/shorter as a result of taking ECP. They should get back to normal by the second cycle. However, this can vary and we cannot predict what each woman's experience will be with ECP.
