Fertility Window ?

I've been on my fertility days really persistently this month and taking my basal temperature 🤒 and I'm still a little unsure as too my specific window I downloaded another app other than this one and the fertile days are a little different as to when we should try to conceive. I've been also trying Pre-seed during my fertility window and we are optimistic, it got good reviews. Picture below shows our work being put in 4 month of trying to conceive😊
