So confused

Candace

My period ended Aug 19th. I’m so confused as to why 3 days in a row now, all 3 tests have been dark. In person they all look the same. The past couple days I’ve had EWCM, my cervix is high, open and soft. I’m on CD10. I ovulated this early last month too. But why are they positive 3 days in a row now? I guess I’m not understanding. Can someone explain to me please?
