I'm dating a younger guy and I'm in my early 30s

I have always wanted kids but lately I'm starting to feel like something is wrong with me because I was married before and with the guy from age 16-30 and never got pregnant and we didn't use condoms. I'm now with a younger man and have told him how important it was to me to have kids one day and that I don't want to be with someone that doesn't want the same. Well  we have been together for almost 2 years now and no babies and I'm about to be 32. I dk what is wrong with me or what to do to become pregnant...
