Advice and encouraging words.

My husband and I are wanting a new addition to our little family. I'm just so nervous and scared that I can't because of the depo shot and birth control rounds that I was on or so long. My periods did come back and were regular minus the length it lasted. Some it was 5 and some it was 7. But has anyone had a similar experience? I try not to think about it and let God take over but some months it's just so hard because I know how bad we both want it. I know I'm stubborn :) I'm young and have many years ahead of me and same for my husband, so I'm not "freaking out" but as far as a baby goes, sooner would be wonderful and later would be rough but okay.
