I got blotto with pregnancy #1 and #3 before I knew I was pregnant, both were unplanned. I didn't find out until around week 6-7 with this one so I had a few drinks again before I knew. Ever since, and in this pregnancy only, I have had a little just once. I know they all say that no level is safe as they just don't know, but my midwife said an occasional glass of bubbly is okay (dont like it though lol) and a friend of mine who also got pregnant after a big night out said she was so paranoid that she did loads of research, and found out that particularly in the early weeks when the baby is in it's little 'bubble' and more supporting itself, its not so bad because its more protected being more of a separate entity. The placenta takes over around week 10 so I guess where they are getting this from? But I guess it makes sense and it is VERY common for this to happen.
