Don’t trust my calendar!

So ttc since April following miscarriage. Always bd’d most during when the app told me my fertile window was.

The past few cycles I’ve instead used cervical obs and cm as well as the app to guess, and thought symptoms of ovulation were after my ‘fertile window’.

This cycle is the same, and opk’s have confirmed - I’m ovulating. It’s cd16. My app always put ovulation as cd12.

Omg it’s like a major breakthrough. Maybe all this time I’ve just not been doing it at the right time. Maybe I’m not infertile. Next week I’m having tests to see if I ovulate, but now I feel positive I do. Just wish it hadn’t took me so long to figure out my own body!
