OPK Confusion

Erikka

I have started really tracking my ovulation, but noticing this happening. I'm still pretty new to this, so thought I'd see if anyone had any advice or has experienced this before? According to the app, I was supposed to have ovulated on February 13. Since I have always been irregular, I never quite know when to test and when not to. I noticed this fluctuation and am curious as to what may have caused it, if anything. I appreciate it!
