When will it happen??

So, I’ve been trying to get pregnant for roughly almost about three years now. I was on the Depo shot since I was eleven or twelve years old because my grandmother believed I was going to be raped (understandable because she was multiple times), but now I’m an adult and I want to start building a little family with my wonderful man. I recently started to take conception plus, which I’m not really sure if it works. I haven’t really had the time to go in to check my fertility, but I need some advice. I’d be a first time mommy. I’ve never got pregnant, nothing. I have an almost regular period, maybe a day or two off. But, I’m really starting to get worried if I’ll ever be able to become a mommy. Any advice?
