Women who are pregnant, those planning a pregnancy, or women at risk for pregnancy should not drink any alcohol.

Alcohol is the #1 drug responsible for fetal malformations. Here is what the Centers for Diseases Control (CDC) say about Alcohol Use During Pregnancy:
"Because no safe threshold of alcohol use during pregnancy has been established, CDC and NTFFAS/FAE recommend that the following women should NOT drink alcohol:

1. Women who are pregnant,
2. Women planning a pregnancy, or
3. Women at risk for pregnancy

Women of childbearing age who are not pregnant or planning to get pregnant should drink no more than seven drinks per week and no more than three drinks on any one occasion.
