Opk help

Hello ladies! I’ve been posting quite a bit about my ovulation tests! 😫 sorry!

I took femara cd 5-9 and started testing cd 11 on cd 12 I had a positive strip test but still flashy smiley on clearblue digital! After cd 12 strip tests were getting lighter & still flashy faces... well I just got a solid smiley (cd 15) so what should I trust more? The strips or clearblue digital?

I’m going in on the 21st for a blood draw to confirm ovulation and afraid now that it’s too soon if Saturday’s test wasn’t actually positive! 😫😫
