I am considering to have another child. However, I think I am too old to have (I am late 30s). What is the age range that I should stop considering getting pregnant?

there's no such "TOO OLD "when you wish to have a child,keep on trying!do anything you can, seek for doctors help,etc. My husband and I are optimistic and thank God .I'm almost 38 years old and currently 16 weeks and 4 days pregnant.Dont give up hope!
