I’m almost hoping for AF

She was due today but no sign of her yet, I got invited to a party tomorrow where I was hoping to turn down drinks and dance around like a pregnant diva... but still I keep getting BFN after BFN. I know I should wait a week to see if AF makes her appearance but I really want to drown my TTC sorrows at this party. Idk if I should cut my losses and have a drink or hold out to test again.
