Fertility

Been trying for over a year with my man, we've tried ovulation tests and apps on the phone and my obgyn telling us when to try but here we are and still nothing.

I've gone through thinking I was to I'm not.

He's getting tested this month to see if he's fertile, and if he is then I will go in But has anyone ever had there man not be fertile and what did you do? Has anyone ever tried the dye test on the female, wondering if I should try that too??
