CM question & help

Me

So it’s cd14 yesterday night when this happened. Never happened before. Wiped a ( I know it’s gross ) snot-like yellow tinted cervical mucus?? I had a positive opk CD 12/13 I say 12/13 because it was late the 12th day and tested early again the 13th day just to be sure it was true positive Today is CD15 and still having really watery/creamy cm. Has anyone else experienced yellow tinted snot like cm?? Is it a good thing?
