I'm sooooo confused! Please answer me.

This cycle I have decided to try maybe baby (saliva test) & OPKs.
My maybe baby result this morning had some ferning (which means I am coming up to my fertile phase) however I done an opk and that had no second line at all - not even a slightly faint line.
What do I go with & why am I getting 2 different results?
Anyone else had this?
