Anyone get PG and never have "fertile" CM?

I just starting charting late in June, and I'm noticing that I have next to no CM... Much less wet or egg white type. I bought some PreSeed to help out during BD. 

Did anyone get KTFU even without ideal CM? I'm getting worried there may be something wrong, or that even though I'm having AF, I'm not Oing because I don't have any CM, or very little sticky CM.  

Thanks for the help.
