Am I getting too old to have children?

No that is not too old. I was twenty when I had my baby and my sister is now 27 and has no desire for them at this time, our society that we liver in says get married and have kids by the time you are 24/25. But look at people in like hollywood, they don't get pregnant with their first until they are almost 40 or so! You will not even be close to too old!
