How much caffeine can you drink if you are pregnant?

According to The American College of Obstetricians and Gynecologists, consuming less than 200 milligrams of caffeine per day (roughly one to two cups of coffee) isn't a major contributing factor in miscarriage or preterm birth.

However, according to a new study in the journal BMJ Evidence-Based Medicine, there is no safe level of caffeine that one can consume during pregnancy. Complications arising from caffeine consumption can include an increased risk of miscarriage, stillbirth, and low birth weight.
