Ovulation and cervical mucus

Cynthia • 20, engaged and ttc.
Okay ladies I've been testing with opks . Every single one is negative. My most fertile days are today and tomorrow. I tested this morning negative. I checked my cervical mucus and it is clear and stretchy. There's not as much as I have seen some of you ladies have but there's more than usual for me . And it stretched to about as long as a quarter between my fingers. I'm assuming that that's fertile ? I guess my question is what do you ladies think ? If my opks are negative but my mucus seems fertile which one should I go by ?
