No Cervical Mucus? TMI

So my SO and I are planning on starting to try during my next cycle and I am wanting to track my ovulation by my CM, but I really don't have any. Like every once in a while there might be a little something, but not typically. What should I do?

TMI: My underwear was pretty wet 13 days after my last period, so I'm wondering if that could maybe be it. Any ideas?
