Ovulation testing and tracking frustration

I’ve posted about this a couple times but I feel like I remain frustrated and confused about my ovulation timeframe.

I am still tracking on this app but now also pregmom. The two differ greatly in the way that it tracks my expected ovulation date and surges.

I’m attaching a few pics in case anyone else has had similar experiences, and potential tips. At I reading the sticks wrong?! Am I testing wrong? My next step will be to get the digital tests if I don’t conceive this month.

Thanks for any advice from others dealing with the same thing. Sprinkling baby dust for all of you in the same boat as me! ♥️♥️
