I will be 6 weeks tomorrow!!

I am very excited and we already told our parents and siblings.
My only problem is we do not know when to tell our friends. Mardi Gras is huge in my city and every year my husband and our friends have a great alcohol induced time. Well this year the Mardi Gras parade is on Valentines day and I will be about 7 weeks and 2 days. Our first U/S will be the following Tuesday. I want to tell our friend there for a lot of reasons,one being because I know they will ask why I am not drinking and another that I am soooooo excited. Part of me wants to wait until after that Tuesday U/S, but another part cannot hold it in this awesome news.
Any thoughts that may help? I know its my choice and I can tell people whenever I want, but it is still hard to decide!
Re: When are you all telling your friends?
BFP on 11/3/11 - EDD 07/6/12 - DD born 6/27/12 via c-section
I have already pretended to drink -- I slyly ordered a soda and cranberry and then people assumed it was vodka and cranberry.
Where do you live? If you don't mind saying. I'm assuming it's not New Orleans since there is only one parade for Mardi Gras?
ETA: I have had a pregnancy end in miscarriage and I was glad my friends and family knew so they could help me through it.
I've told 3 coworkers I'm friends with (who I would also tell if I miscarried) and my sister. Going to wait until after the first doctor's appointment to tell parents. I'm a little worried because my mom will freak with the thought of me having 2u2. DD will be 22 months when the baby is born so close to two! I'll probably tell a couple of close close friends soon.

So I posted their reaction video on Facebook and let the whole world know.
I kept my first two pregnancies secret (with the exception of my sister and a few close friends) until after I went to the doctor. But I didn't want to keep it from the girlies and I knew they would be telling everyone.
Although I did tell my parents right when I found out.
