Help with down there! TMI

Adrienne
Hi Ladies.
I ended my cycle on Monday. AF due again around the 22nd. Today I feel very moist down there where my underwear feel slightly damp. Does this mean I'm approaching my fertile window. Please clarify. This is our first month TTC and I just started paying attention to my down there. We would like to steer clear of OPKs the first month just to see how this month goes. TIA.
