Help?? Plan b??

Before I start I wanna say that I honestly think that I’m not pregnant.

I took plan b exactly 2 weeks ago and my period is due today and it’s not here yet. My boobs sort of hurt and I have on and off cramps. I read online that if you eat pineapple can have a chance of inducing your period so yesterday I ate a lot of pineapple and nothing has happened yet. Every time I take plan b my period is always on time , that’s why I’m freaking out about this one time, cause we had protected sex and just to be sure I took plan b .
