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. I did it with a chart as well as took my temperature every morning before I got out of bed. I saw a pattern after about 3 months so I had an idea of when to 'try'. And doctors recommend that you start on day one of your period or cycle day one and count until day 10, then have sex every other day for the next 10 days. This is a good way to catch the egg! good luck
It's totally not too late and specialmom has some great advice! How long have you been TTC?
