Am I worthless at my age?

I'm 27. My main goal in life is to be a wife and a mother. But I'm still single. I usually go for guys older than me but still close to my age but I hear all the time that older men prefer women in their early 20's because they are fertile and that women in their late 20's or early 30's are less fertile and are only good for just sex. That's just what I've heard. While I won't deny the truth about fertility, it's still not impossible for a woman in her 30's to conceive. Actually more women than ever in US history are conceiving in their 30's and 40's. However, maybe those who did conceive in their 30's already had a long time lover or already had at least 1 child. So I still feel like I'll be pushed aside for some 20 year old girl. I feel so worthless and unwanted and worried that I'll only be use for sex. I feel like I must rush into any relationship. I'm so scared I might not become a wife and a mother. Am I truly worthless? Are their any older men the perfer women closer to their age?
