As a 33 year old woman, I have a different perspective to give you here, I am single, never been married and I have no prospects. I know from personal experience that 10 years ago my goals were completely different than they are now. At that age I wanted kids and marriage and all that. 10 years later here I am single, I want to get married, but low and behold I no longer want children and there are a many reasons for that but that is for another time. At this age don't worry about those things, your life will happen as it should while you are making plans life will most likely change those on you. So what I say is that yes 35 is the age when pregnancies are considered more high risk. I say don't worry about that now, in the blink of an eye you will be 30, I know it feels like just yesterday that I was my self 23, I have grown so much, my thinking, maturity level. You just don't understand that the person you are now is not gonna resemble you in the next 10 years. Just live your life and yes by all means accomplish your career goals but don't worry so much about having kids. Youth is so short, and only life knows what it will bring. So just enjoy being young and when you hit 30 look and see what you think at that time. Enjoy your 20's they will be gone in an instant.
