When I was 43, I found out I was 15 weeks pregnant (unplanned). I was 44 when I delivered my beautiful, healthy daughter. During my pregnancy my doctor kept referring to my advanced maternal age. I think he wanted to keep me aware that I was rather old to be having a baby and that there could be complications or problems. (After I delivered the baby, the doctor admitted his wife, also over 40, was pregnant and she also had a healthy baby.)
Because the labor for my first child (19 yrs. 7 mos. older than new baby) was just under 1.5 hrs., there was a concern that this delivery would be too quick. The week before my due date I was induced. Being induced allowed the doctor to have any possible medical needs ready to roll. I delivered a healthy 6 lb. 9 oz. baby girl 8 hours later. In the room during the delivery was the pediatrician with her staff ready for any problems the baby may have had. I also had student nurses.
The delivery itself was much tougher on me at the age of 44 than the delivery at 24, but worth every minute.
Not knowing I was pregnant for 15 weeks, I was not as conscience of healthy habits as I would have been had I known and still was blessed with a healthy baby.
My recommendation would be to talk to your doctor. Any medical issues you may have could affect the outcome of a pregnancy. But if you are healthy, go for it (with your doctor's blessing).
Good Luck! It is a wonderful experience at this age, quite different than when I was in my 20's. My now 9 year old is growing up with my grandchildren. Cool, huh!
