How to tell when it’s a positive OPK

When I first started using OPKs, I always had a hard time trying to tell which is positive and which are close or negative. Here are my OPKs from this month. (I didn’t write down CD at the beginning, because I was a little unorganized. And my dog tried to eat them. 🙄)

You can really see how the last one is darker on the test side compared to the control. That’s a positive. It also helps to test multiple times a day when they start getting darker.

Hope this can help someone!
