I had my period at nov 3 & ended around 8 nov..few days later i had sex & the condom slip inside my vagina & sperm drop inside me...later about 2 hours i took posinor 2 as recommended by the pharmacy 2 tablets at once..later after 6 days i had a bleeding & last for 6 days...until now i waited for 31 days for my next period to come..lastly i got the sign of period comin..a little blood..but only for 8 hours my period stop...what does this means isnt the effect of postinor 2 delay my period again or is this the sign of pregnant..i did a pregnacy test..but negatif..could this be the postinor effect to the delay my period
