So confused! Please help

Yesterday morning I got a peak result from my clear blue ovulation test. So in the afternoon around 5 pm I tested with the cheap opk strip and it wasn’t quite positive (although my lines were darker than any other day). So I didn’t think I reached my positive ovulation since it was negative. Then today and tonight I took another cheap opk and both were real negative (my lines are getting lighter) so question:

1. Did I miss my ovulation window.? Between 6:00 am and 5:30 pm was my surge gone already?

2. Or did I not ovulate this month?

3. Or should I keep testing or no point since it’s getting lighter?

I am just confused with the peak result from clear blue and then the negative result from the cheapies. Anyone have any experience with this ?
