Caffeine
One 8-ounce cup of coffee has 95 milligrams of caffeine and a 1-ounce single shot of espresso has 64 milligrams. Consuming too much caffeine can make you restless, anxious and irritable. It can also interact with certain medications. Pregnant women may need to cut back on caffeine consumption. While moderate caffeine consumption doesn't appear to cause miscarriage or preterm birth, according to The American College of Obstetricians and Gynecologists, it's still unclear whether high levels of caffeine consumption have any link to miscarriage, according to an article published in the August 2010 issue of "Obstetrics & Gynecology." Speak with your healthcare provider if you want to know if caffeine is safe for you.
