Still no positive result ovulation test?! Cycle is usually 32-34 days!

Claire

I’m on cycle day 21 and i still havent ovulated. I’m testing with opks since day 12snd still havent gotten my positive. My cycle is usually 33-35 days. I ovulated as normal last month on day 18. Could I have missed my ovulation day? I’ve BD everyday so I’m not too worried about missing it.
