What kind of CM is this?

I'm on CD83 right now, started taking vitex a week ago and hoping AF will rear her ugly head soon. I know EWCM is most fertile and anything else really isn't, but this is like a mixture between EWCM and creamy. it's stretchy but milky white, not clear like ewcm, and my cervix is soft and very high, feels sort of open, I always have a difficult time determining openness but I could fit the very tip of my finger inside. Is it possible this is fertile CM?
