Au-pair family, is it a scam???

just a few days ago I got mail that was similar to the one you got. actually they were asking me the same questions and just changed some details that fit what I wrote about me. Now I regret I ever answered to that email, I even sent them some photos of mine but at least I didn't send any personal info which they actually asked for later and even asked for a copy of my passport. I got this email from [email protected].
I searched the internet and found a profile of another family also from Valley Stream with a 4 year old daughter Britney.

I have had exactly the same email....in the last week and sent all my details.... Should i be worried???
