Drinking up to 1 cups of coffee ( less than 100 mg caffeine) per day is
unlikely to harm the unborn fetus.

However, an analysis of several studies concluded that there is a
small increase in the risks for spontaneous abortion and low birthweight babies in pregnant women consuming >150 mg caffeine per day
[1,4] .
More recent studies have concluded that excessive coffee consumption
may increase the risks for early pregnancy loss stillbirth (greater than 8 cups
per day) [2, 3].
