Watery vs Eggwhite CM

I've seen some websites say watery mucus means you're fertile. I've seen others say eggwhite/stretchy mucus is more fertile. Then I've seen some use the term interchangeably. It's starting to get confusing. Is watery alone enough? I've had watery CM for a few days now and just started getting "High" on my Clearblue Advanced Digital ovulation kit (no Peak yet). Anyone else experience this?
