Worried...

I am 20 years old, my fiancé & I just bought our first home together a few months ago. He has a beautiful daughter already who I say is mine as well. Might as well be. We've been together since she was 8 months, now she is 2 yrs old. She wants a 'bubba' she says. I just finished up school becoming a medical assistant. When I was 16 years old which is young I know, I got pregnant but had a misscarriage. I got really bad infection in one of my ovaries & had to go get shots of strong antibiotics to cure it ect ect. They said it may very well affect me in the future but not for certain. I was on the depo shot for a few years & got my last one over a year ago. In January 2015, after still not having a period after stoping the shot my dr told me that was normal it sometimes takes a long time for people to take back... So I start having really bad cramps, hurting, I go to the bathroom & long behold I was indeed pregnant after taking test that had said no. I went back to the DR she did tests & confirmed this was a miscarriage. We've been trying non stop, I've been being super cautious about EVERYTHING, no drinking, I don't smoke, don't use drugs. I'm a active person. We recently checked into going to a fertility clinic. Which is very expensive. My younger & oldest brother both have children. My older brother & my aunt can't have children. I'm stuck between going to the clinc & getting testing done, or just letting it all play out. I know it will happen when the good Lord is willing if it's going to but the wait & not knowing is killing me. I know it can take a long time for some people to become pregnant after being on the DEPO, so I'm wondering if any of you were on it, and how long it took for you to become pregnant after stopping taking it. Any tips? It's really depressing im sure a lot of you can relate. Thanks!
