Oh gosh, you are not old. LOL Nowadays, many
women have kids until
40 with absolutely no intervention. I had kiddos in my late 30's with no children prior to that. What you can do is be really proactive though. Take care of your body, get to a good weight (not too thin or overweight), eat well, exercise, get your sleep, de stress your life. I gave up caffeine when TTC. I tracked my temperature so I best understood my cycle.
