has anyone ever experienced this?

I'm 7dpo 1st month trying after my miscarriage for baby number 1. I'm in habit now of checking my cm and today when I've checked it it's still the consistency of ewcm but it's going a more milky colour? I've never seen it like this. Does anyone know why it's like that or if it's a good or bad sign? Trying to hold out till 12dpo till I test
