Positive OPK but no “Peak” detected this month


I’ve been tracking my ovulation with OPKs for 5 months now. Usually I get a positive, which is followed that day but a SUPER strong positive. This month I DID see my positive but never saw the peak. My urine was also pretty diluted because I’ve been trying to flush out a sinus infection.

Do you think this could mean I didn’t ovulate? Or is a positive OPK enough to ovulate even without the test line being darker than the control?
