What age???

Im 33 years old and I have a 4 year old,awesome energetic handsome son. I recently had my divorce finalized in Oct.2014. I have been very blessed to find a loving,caring,gentle man,who loves me & my son unconditionally. We are getting married on Christmas eve 2014". We are also trying to bring a healthy baby into our family as soon as possible. What age is the oldest that some of you ladies 1).Conceived/carried close to full-term, 2).How old were/are you once your child/children were born 3).If you have other children, do you think this pregnancy was harder or easier to conceive/be pregnant/delivering??? Please help me ease my fears. I'm extremely scared I'm getting to old for one more child. Thank you & God Bless You All.. Praying for each of you trying to conceive,who are pregnant & those who just had a baby!!!?????
