Suggestions for wondfo opks!!!

Malorie • Trying for baby # 1 on month 11 now.
Hey ladies! 
​Looking forward to hearing some tips or tricks of the trade using these things! Perhaps time of day to test and how many times to test! I'm new to these opks. And haven't had much luck with clear blue digital. Hoping I can pin point ovulation so any suggestions can help. Thanks again! 
Baby dust to all of you!
