Need opinions on my charts

So i have 4 diff apps i use for ttc. Ava, fitbit, fertility friend, and glow. Attached r my 4 charts with fitbit just tracking my resting heart rate bc ive read that elevated heart rates could indicate pregnancy. Normally mine is lkke 65-69. Glow is saying 4 dpo, ava says 6dpo, and ff says 9dpo so whag dpo am i really?! Any opinions wld be appreiated! Do my charta look promising or shld i expect af to show next week?
