AF due today but no show, took pt and bfn 😕

Lupita • married an anime junkie like me. Love to watch 90`s sitcoms, and draw, paint, cosplay. my fav 50"s sitcom is i love lucy. my fav disney princess is jasmine. looking to make newfriends.
My expected af was supposed to start today according to glow but no show yet. Took a pt and got a bfn 😕 not sure what's going on. Going to wait a couple more days and see if I get my period. Might take another pt in a couple of days and see if anything changes.
