Can anyone make sense of my chart?

Caro • At age 41yrs Baby #4 born September 2022 thanks to Glow tracking!

Hi everyone I’m new to the app and pretty new to using OPKs on my TTC journey.

I am 41 and we decided to stop trying after this last cycle of 2021…

So I’m currently waiting for AF (whilst praying for a BFP!) but I can’t even work out which day I ovulated because the Clearblue Digital gave me the flashing smiley face on Dec 19 then again Dec 22 and again Dec 25…

Can anyone make any sense of this?

Thanks
