Calendar and ovulation tests sync but CM does not

Hi all!

I have been actively ttc for 6 cycles now with no luck. I have been using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and ovulation tests. I started with the strips from amazon and am now using digital tests. I’m starting to think the strips may not work for me. The last two cycles I’ve been paying closer attention to my cm and I’m finding that my egg white cm is coming days after I get a positive ovulation test. To clarify I may get a strong positive or peak fertility smiley on day 12 or 13, then my glow calendar usually supports this with a predicted ovulation in day 14. However I’m finding I don’t get my fertile cm until around cd 20. Does anyone else find this is happening to them? Should I go by the test or my cm? I’ve also tried temping but honestly it’s too cumbersome for me so if possible I’d like to avoid but I’m willing to pick it back up if you all think it will help clarify things for me.
