Absolutely nothing wrong!

Hi
So I'm ttc baby no.2 (for over 6 years now).
I'm ovulating, had ultrasounds inside and out and my ovaries are fine, my husbands test show he's fertile.
So there's no reason I'm not falling pregnant! Can't have <a href="https://glowing.com/glow-fertility-program">IVF</a> as can't get it free and can't afford to pay. Presume no point in having Clomid etc as I'm ovulating.
Anybody got any thoughts? In same situation?
Thanks :) XX
