Opk frustration

AJ • SAHM of 2 (👦 4YO, 👧 5YO) Oh yeah, I have a husband too lol.
I'm not are if I should splurge on the next months opks to get the clear blue ones but I am so frustrated... I've been having ovulation signs for the past week and still nothing on these tests.  Days from left to right, farthest right is fmu this morning, I take one in AM and one PM.  yesterday's are darkest but still.
This is what my bbt charting has looked like for the past week.
