Limit Your Caffeine

The National Infertility Association Resolve thinks there's reason to be cautious. It says animal studies suggest that caffeine can prevent an egg from maturing properly and since a less mature egg may not fertilize, it may affect your chances of getting pregnant. Limit your caffeine intake if you're having trouble getting pregnant. One study did find that 200 mg or more of caffeine a day (roughly the amount in a 12-ounce cup of coffee) raises your risk of miscarriage, so this would be a good time to start cutting back. The American Congress of Obstetricians and Gynecologists says that less than 200 mg of caffeine per day doesn't seem to raise the risk of miscarriage.

You'll need to be aware of other sources like tea, soft drinks, energy drinks, chocolate and coffee ice cream. Caffeine also shows up in herbal products and over-the-counter drugs including some headache, cold and allergy remedies. Read labels carefully before purchase a product.
