Hi, I had an unprotected sex 4 days after my last period. Then I took postinor 2 3-4 hours thereafter. Now 7 days after I took the pill, I started bleeding, lingered on for 3 days. It's not as heavy as normal regular flow but I still used tampons. The bleeding started when I was ovulating. I had 14 more days before my period starts but with this bleeding, I don't know what to expect. Also I have been taking postinor 2 for some years and this the first time I experienced bleeding after its usage. Other times its been a delay on my period with 2-4 days but have never bled. I am worried.
