I also read your last post, but only now feel moved to comment. I do agree with previous posters, and feel that the drinking thing might be a smokescreen for something else to be honest, particularly as you seem not to want to hear that everything will be fine. Are you looking for a reason to abort?
If it helps, I drank an absolute skinful a couple of times before I POAS - and by that, I mean spending a whole day drinking beer with friends (got through about 8 cans), then on to a bar where a scary amount of rum and vodka was consumed, then home to a couple of glasses of wine. In one day.
I also used to drink a good couple of glasses of wine per night - big glasses. Obviously, as soon as I found out I was pregnant (at about 2 days after my period should have been due, so 4 weeks 3 days after LMP, I stopped drinking, and have only had very occasional, small glasses of wine here and there since then. I didn't worry at all about what effect my drinking very early on may have had, because like many people have already said, the baby is self-contained at that point. It's also more than fair to say that many babies are conceived in a drunken haze, and before the advent of early detection tests, a lot of women had no idea they were pregnant until missing at least one period.
There is an awful lot of scary propaganda out there about FAS, but it really is only an issue for women who drink a lot on a regular basis during pregnancy. A blowout early on is totally different. I asked my doctor about my two big drinking days before I found out, and he said that if I had done any damage at such an early stage, I would miscarry.
If FAS was as big of a thing as many people would have you believe, then why is it that our parents' generation, whose mothers were told to drink Guinness daily to "keep their iron up", aren't a bunch of deformed-faced mentally disabled people?
Again, FAS is only a worry if you are an alcoholic who continues to drink very substantial amounts throughout your pregnancy.
But be honest, that's not the answer you're looking for, is it? My thinking is that you, for whatever reason, don't want this baby (which is perfectly fine, by the way), and are looking for a "way out" that absolves you somewhat of making the decision.
