TTC help!

 I'm charting on fertility friend, but it's just confusing me hahaha!  Cervical postition and cervical fluid are all a go for ovulation, but my OPKs are blank. Not even a hint of a line! What is going on here?

the cheap opks arent always reliable perhaps, Id go with what your body is telling you instead and maybe invest in a digital tester they are more accurate.

 ty. They detected a surge today, I was too antsy lol.
