Help! Weird cycle

Jennie • TTC #1 👶🏻🍼 baby dust!!
I'm looking back over my past cycles and am noticing something really weird in October. The first fertile window is fine but then the second fertile window backs up to the last day of my period when it usually has some space in between the pink and greenWhy would it do this? I don't have pink next to green anywhere else in my cycles
