Can someone help me??

This month I decided I wasn’t going to track my ovulation. But I then changed my mind 8 days after my period. I toke a ovulation test yesterday morning and it was super close to been positive. I toke one this morning and it’s a faint line (negative) My app says I’m due to ovulate in 8 days.. I know apps aren’t always right. I’ve have irregular periods ranging from 28-38 day cycles. This cycle was 38 days. My last period was 8 days ago.. I do understand you always have some what LH in your system but I’ve never got a “almost positive” for it to turn negative without peak. My surge is never a short surge also. I normally have positive opks for 3-4 days straight.

Is there a chance I missed ovulation in the 8 day bracket that I wasn’t testing? Or has this happened to anyone else?
