Trying to conceive with no luck

My husband and I have been together for 5 years and not once practiced safe sex. We were recently married and are still trying to conceive, with no luck :( I almost feel like I can't get pregnant, I've wanted to be a mom since I was 4 years old walking around with a doll dressed as a baby and a veil on my head. Now that it's my turn I guess I'm nervous. I know that anxiety can contribute to non fertility, but Damn...5 years! And no baby! Help! I want to avoid fertility treatments so any advice would be appreciated. Thanks so much!
