First cycle using Ava again

My husband bought me Ava back in 2018 but by the time we got it I was already pregnant again. We tried using it again after a 2nd loss but after a month or two the bracket stopped syncing so I left it alone. Now I'm back and ready to learn my cycle and hopefully conceive our rainbow 🌈 👶.!. This is my first cycle using ava and AF is due within 2 to 4 days (depending on which app i believe)

Here our my charts (ava and ff)

Does this look like a did O ? I plan on using opk next cycle. I also read somewhere that sometimes the body/skin temp doesn't rise but pulse does? I'm not entirely sure how it all works and I've read the ava guidelines many times.
