Blank LH strips?

Ya’ll. I feel like I’m crazy. I’ve peed on 5 OPKs in the last 3 days and they all look the same. To the naked eye they look straight up blank like a negative pregnancy test. With a phone flashlight I can sort of see a tiny line. How is my LH level this low consistently at 1:30pm and 8:00pm on cycle day 11 of a 26 day cycle? Starting to be a little freaked out about it but I don’t know why. Probably just means I ovulate later than I thought.

Whenever I see other people’s OPKs I never see them as light as mine. I am using the Proven brand from Amazon. Anyone else experience this?
