You may not like to hear this but women having a kid past 30 introduces a lot of potential problems and deficiencies in the child.
Only past 40 do you go into ‘really need to check’ territory.
Post 35, most couples should have a serious talk about kids. There’s a healthy chance that you’ll run into some problems either conceiving or carrying the fetus. Every aborted attempt can cost you months or more - a luxury you might not have if you’re touching 40.
