Praying hard

Af on one App is due today- on glow due tomorrow. Yesterday had very very small amount of pink discharge in morning and nothing for rest of day (day before that DS and I had sex then I woke up to the pink discharge) could it just be af coming or did someone have simular experience and get a bfp? I don’t want to test till Monday if I miss af. Praying hard. No symptoms either mild cramp here and there. Boobs a little tender (one side more than the other) and that’s about it !
