As tempted as I am to riddle off statistics to you simply because I like statistics and happen to know a lot of them on this matter....I won't.
But what I will tell you is what I told my sister when she was in the middle of post partum new mother shock.
Most people who have children, whether it was planned or not, whether they are rich or poor, whether they are young or old, don't regret it later in life. They may regret the situations under which they had the children, but they are almost always glad to have had them.
I think you should take the applicable safety precautions, and other than that, I don't think you should worry about anything.
