Cervical Mucous Method help

[lisbonlovesjacq.livejournal.com]

So, I am somewhat understanding of how the cycle goes..

week 1: period
week 2: dry and tacky and white.
week 3 (ovulation): plentiful, stretchy, and clear.

Now, what exactly is week four supposed to look like (post-ovulation but pre-menstruation)? Does is stay the same as the ovulation mucous or is it supposed to revert back more towards tacky and white?
