It is not recommended for pregnant women to drink coffee during pregnancy and try to minimize the amount of coffee they drink. Excessive amounts are unsafe for the fetus. Usually, coffee consumption in small amounts by pregnant women does not usually affect the fetus. However, if a pregnant woman consumes too much coffee, it may also lead to miscarriage or premature labor. What is the safe amount of coffee to drink? According to a study in the United States, the rate of miscarriage doubles when the amount of caffeine in a cup of coffee exceeds 200mg per day. However, the rate of miscarriage did not increase when the daily caffeine intake did not exceed 200mg.
