Hate the uncertainty 😪

Hi all, so according to my three period tracker apps (yes 3..) 2 said I should've stared AF Saturday the 13th, & 1 said I should've begun Monday the 15th..Well all 3 were wrong and I have yet to get it. Of course I was excited & began to think this was IT! but I took a test and got a BFN yesterday morning which soured my wishful thinking. I'm scared to take another one but have yet to get AF...I'm still holding onto a little shred of hope but also have had a period show up 3 days late before so am anxiously awaiting what's going to happen next...Just needed to vent a little 💗
