Hi, I took postinor 2 twice in the last month, on the 1st of this month I had unprotected sex and it so happened that I was also ovulating, so I took postinor 2 immediately. I've not had withdrawal bleeding or anything (this has happened before), so I did a urine pregnancy test 8 days after unprotected sex and it came back negative. Although I feel strange,do u think there's a possibility of me being pregnant?
