have I missed my ovulation peak?

For the last 4 days I have had ovulation pain but all the clearblue advance tests say low fertility? I'm tracking ovulation at the moment to increase my chances of a pink pregnancy as already have 2ds. We have sex with a condom as ideally planning pregnancy for August/Sept. I can't work it out?? Glow keeps moving my ovulation dates due to logging low fertility so I'm all over the place? Could I have missed my peak?? Any help would be appreciated 😕😕
