caffeine and its effects on pregnant women
For women who are pregnant or trying to become pregnant, consuming moderate amounts of caffeine does not affect chances of miscarriage. The nausea commonly seen in pregnancy may create an erroneous association between caffeine consumption and miscarriage. In fact, nausea due to pregnancy leads to coffee aversion by some women, having a self-regulating effect. Several women's health organizations agree that moderate caffeine consumption is safe for pregnant women. The Organization of Teratology Information Specialists (OTIS) states in informational resources on their Web site that consuming up to 300 mg/day of caffeine does not affect miscarriage.
