@ZipLine-- What about your partner? Is he making lifestyle changes to improve male fertility as well? Because pregnancy requires both partners to be healthy individuals. If your partner's sperm count, quality or mobility is low, you might not get pregnant even if you have many healthy eggs and a suitable environment for a baby.
I recommend an organic diet with lots of fresh fruit and veggies, daily walks, meditation and a multi-vitamin supplement for both of you. Just doing these will improve your fertility greatly.
