After reviewing the available information, there is no type of alcohol that is considered safe during pregnancy. According to the Centers for Disease Control and Prevention (CDC), there is no known safe amount of alcohol consumption during pregnancy, and there is no safe time during pregnancy to drink alcohol [2]. Drinking alcohol during pregnancy can cause a range of disorders known as Fetal Alcohol Spectrum Disorders (FASDs) [2]. FASDs can include physical, behavioral, and learning problems with lifelong implications [2].

The American College of Obstetricians and Gynecologists (ACOG) recommends that women who are pregnant or trying to become pregnant should abstain from alcohol [1]. This recommendation is supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) [1].

It is important to note that even small amounts of alcohol can be harmful to a developing fetus [3]. According to a study published in the Journal of Studies on Alcohol and Drugs, drinking as little as one to two drinks per week during the first trimester was associated with increased risk of having a baby with a low birth weight [3].

Therefore, it is recommended that women who are pregnant or trying to become pregnant should avoid alcohol consumption entirely [1][2][3].
