Rant...af late..due 11/18..

Kelly
I'm 4days late counting today! Test says BFN! AF was due 11/18.. Its 11/21 today and I don't know if I'm late because of stress, or the app is wrong in tracking, yet my other 2 apps say I'm late as well.. I pray I continue to be late.. And that I get my bfp soon, what do u think ladies??
