Ovulation late cyle ? PLEASE HELP

Hello, my temps are at the highest point in my whole cylce the past few days 36.57.. i had a big drop inside the green where I felt my body tried to ovulate temp went up but just geared up and done it again..

I have a question though. I have roughly a 35 day cycle. AF never comes on exact day always few days later,

I had a 42 day cycle last time because I had a Chemical pregnancy.. another app called Premom app recalculated this cycle to be a 42 days cycle and the ovulation prediction was yesterday but based on temps it would of been the day before that so maybe I am having a 42 day cycle again ? Or is this a fallback rise from the temp in the green ?

But if I was to have a 35.. my chances of pregnancy would be slim because of a short LP ?? As 35 day cycle would make me due in 6 days.

Someone please help me :(
