Hi maryann, last jan 22 i took 2 tabs of postinor 2 at the same time and took another 1 after 12 hrs and bled after 6 days. I'm supposed to have my menstuation last feb 6, but until now it hasn't come yet. I don't feel something in my body, i don't even have any signs of having my period. Am i pregnant or is it just the emergency pill which has affected my cylcle? Please help me out, as I feel so anxious with this. Thanks for your kind response.
