I have my little boy when I was 34 years old. My mom had me when she was 33 years old. If anyone could control when to have a baby, by all means, plan that according to your "schedule". The reality is, not everyone is "lucky enough" to have that control.
Go for it since you are having the thought of having a child. Why wait? I wouldn't call it aging when you're only in your early thirties. However, as we get "older", the longer we wait, the less chance we can get pregnant. Getting pregnant is not as easy and instant as drawing up a grocery list. You have to start eating healthy, taking prenatal vitamin...etc. I've been doing that for 5 years before I could actually get pregnant!
Time is ticking, just do it.
