Wondfo opk HELP!!! πŸ˜’

Camille β€’
Grrrr... Are opk's as hard for u to read as they are for me? The test line never gets as dark as the control line! I honestly have no idea when I'm ovulating because I am having the hardest time reading the tests! went in for blood work last month and showed i ovulated despite clear blue and wondfo opk kits showing no ovulation! Any help would be appreciated :) thanks ladies!
