AF 6 days late after taking morning after pill ??

I had unprotected sex 2 weeks ago on May 23rd . he accidentally came inside me & I wanted to get a plan b immediately but I couldn't because of certain circumstances . I didn't end up taking the plan b until about 2 1/2 days since he came inside me . I always have a 31 or 32 day cycle so right now I am 6 days late for my period . is this normal ?? I was going to get a pregnancy test if AF doesn't show up in 2 days but I'm just freaking out 😩 I don't have any pregnancy symptoms . just sore boobs from what I hope is AF coming . does anyone think I might be pregnant or am I just late ? has anyone ever had AF come a week late after taking plan b ?
