Need some advice please!

Hello ladies! I was on the depo provera shot from 2009-November 2014. Which means the shot began working out of my system around February of 2015. I didn't have a period the whole time I was on the shot. I never even had spotting. I had gotten married this past December & my husband knew from the start that with how long I was on the shot, it could cause issues in the long run when we began ttc.. Is there a way to check to see how fertile I am? Or if I can even produce eggs? We've never used condoms before. But I've also never gotten pregnant. Any advice will be appreciated!
