How much damage does drinking alcohol in the first 3 weeks of pregnancy do?

It's natural to worry that your lifestyle before realising you're pregnant could harm the baby, but in reality it's very unlikely to have done any damage, especially as you've realised you're pregnant so early and can make all the necessary changes to your diet to give your baby the best start!

Don't worry! I did the same with my 1st child, I drank a few beers and a shot or two for Thanksgiving and 2 days later I found out that I was pregnant. I had a perfect baby, 8 pounds, 2 ounces, 21 inches long and he was 2 days overdue. He is now 9 years old and he is VERY smart and active!
Drinking causes low birth weight and early delivery, and many physical/mental complications, I only drank that one time while I was pregnant (before I knew it) and nothing happened.
Don't worry sweety! Just dont drink anymore, and if you smoke STOP!
Good luck to you, and CONGRATULATIONS!
Take care

PS I was only about a week and a half pregnant when I had those drinks because I took a pregnancy test 2 days later and then went to the dr a week after that and I was almost 3 weeks along!
Again, don't worry, just don't do it again until you have your baby, or until you are through breast feeding, if you choose to do so.
Good luck again!
