Where are my CM experts??

Okay, so I'm on CD 12 of a 28 day cycle and for the past 2 or 3 days, my CM has been increasingly watery. Now today, it's had a white/cloudy look to it but is still thin and watery. I feel like it should be changing to EWCM soon, shouldn't it? Is this kind of CM normal before that comes? My cervix is super high and super soft, I can barely differentiate between my cervix and my vagina walls but I'm just concerned about my CM. My opk's started off stark white and have been getting a little darker over the last two day but no positive yet. Any insight you can give would be fantastic 😘
