TTC Ovulation Issue?

Hi everyone! My husband and I have been TTC since January, (which I know is not that long) but I haven’t gotten that POSITIVE ovulation test the past two months. I’m using pregmate ovulation tests and idk if it’s user error or if anyone else has run into issues with their ovulation tests. The darkest test I’ve gotten is around CD 14.

Should I go see my DR to see if I may be having anovulations or don’t ovulate at all? This is causing me stress and I don’t know what to do!

My cycle is anywhere from 30-35 days. I have been doing 2 tests daily! Around 11 & 7p
