Taking over my life

I hate being asked when we're going to have kids. I feel like such a loser saying oh we are trying. All of my friends and family are having babies and I'm so happy for them but it hurts so bad that I'm not getting pregnant. I was on birth control for over 10 years my doctor says not to worry. My doctor and gynecologist both say I'm in good health and that I should just relax. People always say relax and you'll just get pregnant. How my supposed to relax when there's nothing in the whole world that I want more than to be a mother? All I want in my life is a baby. How my supposed to relax and just let it happen? I feel like my whole life is just revolved around my ovulation and waiting for a missed period and taking ovulation and pregnancy tests. This is stressing me out even more. How do you just live and let it be? How do you just relax and let it happen? I'm turning 30, I know that's not too old, but it took my mother 10 years to have me. How do you stay de-stressed.?
