I am a healthy, nonsmoking, married 29-year-old woman who drinks occasionally. About 2 weeks ago, I had 5 or 6 drinks at one time and threw up repeatedly afterward. I do not normally drink anywhere near this much and have only been sick like this one other time in my life. The worry is that I think I may be pregnant. If I am in fact pregnant, I would have conceived around this time. Could this kind of drinking episode damage the fetus so early on in its development? For instance, would I need to worry about fetal alcohol syndrome?
