Can Plan B make your period late or even miss it?

I took Plan B awhile back and I haven't gotten my period yet...I'm 11 days late.

i don't if it's because I haven't gotten it yet but my mood swings are horrible.

My bf says there's nothing to worry about. I know my body better then anyone else and this isn't normal. I have never took plan B but he was BEGGING to finishes in me so I gave in.
