not where I expected to be at this age

Do you ever feel like you're behind from where you aimed to be? 

Growing up I always imagined my life as married at 23 and kids by 25. I just had my 24th birthday and although I don't have a man in my life, my ovaries are screaming and I just want to have a baby. I don't want to make another man feel trapped to me because of a baby however I feel that physically and psychologically I am ready for the next phase of my life, having a baby. 

I have lots of experience with children as I am a career child and youth worker until I complete my education to be a psychiatrist.  Just wondering what other people's experiences are coping with this feeling.
