Is anyone a consistent wondfo opk user? I have used them in the past and thought they worked pretty well for me. I started using them last week and they have been staying/drying dark, sometimes positive. So I found a sheet with directions and it says to read results after 5 min and if you read later it can cause a false positive. So now I'm wondering if I've been driving myself crazy thinking these are staying positive. They have all been really dark at 5.min prob but possibly not positive.
pic is at 5 min then at 30 min
