Hi 2003 - I don't have much to add that's really positive for you, but I have a book which goes into quite a bit of detail about the risks of alcohol in pregnancy. Basically, there is no PROVEN safe level of alcohol that you can drink in pregnancy which is why the advice is not to drink at all. Some people, however, say that a moderate amount of alcohol won't do any harm - there is no actual evidence that a small amount of alcohol harms the baby.
The trouble with trying to give more specific advice is that the only studies are observational ones (i.e. they can't run clinical trials, because that would involve asking expectant mums to drink different levels of alcohol and measuring the impact on their babies - who's going to volunteer for that experiment???). This means that the effect of alcohol gets mixed up with other factors that can't be controlled. For example, you might drink a lot because you're stressed, and it might be the stress that affects your baby rather than the alcohol.
This is a rather long-winded way of saying that the blanket DON'T DRINK message hides a lot of uncertainty about the effect of alcohol on a pregnancy. There's every chance that your baby won't be affected at all - it certainly isn't a given.
The symptoms of FAS, by the way, range from facial abnormalities to limb damage and heart defects. It won't be possible to eliminate all of these before the birth, but a scan should have revealed whether it was a good size and had a strong heartbeat, so these are two less things to worry about.
My friend was told by her doctor that he had cared for several alcoholics during their pregnancies (I'm not suggesting you are one, btw) and they had delivered perfectly healthy babies.
Sorry for the long post but I hope there's something in there that might help you. I think that if you've just found out your pregnant with only 7 weeks to go, you'll find plenty of other things to think about which should take your mind off the worry!!
Wishing you all the best and praying that it turns out well for you.
