Why are mine bleeding? Hello, Am Ella, I saw my period on the 29th of August - 1st of September, had unprotected sex on the 4th of September, thou he did the withdrawal method but I wasn t sure enough then I took postinor 2 to be on a safer side. It was taken between 24-48 hour. But am presently bleeding, 7 days after taking the postinor and it started on the 11th of September and doesn t look like a period because it s light. My period was suppose to be on the 25th of September. This is my first time of taking postinor 2 and am scare. Could it be that something went wrong?
