What's your opinion

So according to glow my AF is supposed to show today. I have no symptoms except for sore breast. But according to another app my AF was supposed to show yesterday I took a tea a couple days ago got a bfn and I took one today as well and got a bfn. My question is should I count my self out for this month and ttc next month or do you think I could still get a bfp soon if my AF doesn't show in the next couple of days?
