Hy, I Took Postinor 2 After Unprotected Sex, Then The

Hy,

I took postinor 2 after unprotected sex, then the next week I was on my period, we was using a protection but it bursts and some poured inside of me. I took postinor 2 with original ampiclox tablet same day, but my period hasn't stopped its almost say 9 days now..

I don't know if its because I stopped breast feeding same week I can't tell y but I know this isn't normal please I need your advice, do I stand risk of still getting pregnant???
