What day would you consider ovulation?

In the 18 months ttc I have NEVER gotten an lh strip this dark and for this long. Even last June when I did conceive (ended in mc) it wasn’t this strong. We’re going on 10 hours of a blazing lh positive. Even Premom knows my lh is never super high (been charting for 5 months now) so it rates anything over .5 as high fertility for me. I feel like its rattled me so much I’ve forgotten everything I know about ttc. Glow and Premom are predicting today as ovulation. What day would you consider ovulation? Would it be today since my lh onset started yesterday or tomorrow since I got my peak today? Does anyone have the lh explanation chart? I thought I had it saved but can’t find it.

This was my 4th round of 2.5 Letrozole, 1st month on 500mg metformin twice a day, 4th month on Power Prenatal +CoQ10 Boost by Bird&Be as well as 4th month on Ovasitol. I’m on my 7th month doing Creighton Model charting and am on my 6th day of fertile type mucus, yesterday being a level 10ckl. We have been trying to stick to the every other day method suggestion from my doctor. So far we have bd cd6, cd8, cd11 and cd13. Tonight is the last day we can bd as my husband is doing a semen analysis Thursday.
