Add me to the list.
I had a huge night out clubbing when would have been about 4 weeks with my daughter. Had my last drink at 5am and was sick for two days after. Even worse I continued to drink throughout the next week - it wasn't until my period was nearly a week late that it occured to me I might be pregnant. DD is fine
When I asked my doctor about it at the time I was told not to worry because the baby does not connect to your blood supply until about 6 weeks into the pregnancy - before this it is a self sufficient little unit so you're not actually pumping alcohol into it like you would if you were further along - at 4-5 weeks the placenta is not even developed or functioning. So try not to stress to much everything will be fine
