Help me, Please.

I have been ttc #1 for 6 months now and have just recently started tracking my cervix position. I ovulated  on the 22nd of May and I am still tracking cervix so that I can get more comfortable and can tell the deference. So today I checked and it is hard and high. AF is due to come on June 6 and from what I read on the Internet, it says right before AF the cervix will be low. What could this mean?
