BFP using Opks’s

For those of you who used Opk’s and got a BFP, drop your period/<a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation calendar</a> showing when you ovulated and the days you BD’d prior to it! I’m curious to see how different everyone’s is. As I am ttc using opks and having no luck.
