Trying to decide when to take a pregnancy test based on my chart

So my opk positive didn't really coincide with my bbt rise so I'm a little confused according to fertility friend I'm 8dpo but if ovulated where I think I did I am 12-14dpo my luteal phase is around 12-14. I think I ovulated cd 13 or 15.
