Is it possible to not ovulate?

I’ve been using clear blue advance opk for two months now. First month, got my PEAK after 5 days of HIGH... this month, I am on day 8 of HIGH and the glow app says today I should ovulate, but just still getting HIGH and not PEAK results... the packaging says in their research they 25% of women had 5-9 days of HIGH before peak, 66% 1-4 days and 8% no peak at all.

Anyone else have experience with this brand / type of test? Could I still have hope I’ll ovulate this month?

**background: my cycles were extremely predictable and reliable, until I had my second miscarriage... it’s been 4 months and I’m still all messed up**
