egg white cm before af? or preggo?

I check my cm religiously and I'm on cd 29 (normal is 32) and ttc #2 on our 3rd month of trying and I've had yellow snotty mucus for a couple of days, even this morning and now I have almost clear ewcm but I'm still fairly dry. Did anyone experience this and get bfp after or af?
