Help..

I Took The Plan B Pill TWICE in 1 month ( yes I am aware of how bad it is but hey we all have those moments where there's no other option . ) So This Month I Am Late on my period by 11 Days ! I have took pregnancy test The result is Negative . BUT yet no period . Should I be scared of ending up pregnant or is my period delayed becuase of the plan b Pill plus all the stress. Help please !

( no rude comments please . )
