TTC!!

I’ve been trying to conceive with my fiancé for about a year and a half. A while back I decided to try and track my ovulation with the clear blue ovulation kit and I hadn’t gotten any positive ovulation tests. I recently bought the pregmate ovulation kit off Amazon and I’ve been track daily since I started my last period. We haven’t used any protection in the last 2 years and I’m starting to worry I can’t get pregnant again. With my son I had an extremely hard delivery because my doctor didn’t do what she should have. I don’t know if anyone has any tips or if I just need to keep tracking daily for a couple months to see if I’m even ovulating. And what could it mean if I’m not ovulating at all..?
