Do you know of any online communities for miscarriages?

I had my first miscarriage in May 2009, then my second in July 2009. I thought I was over it, but I guess I'm not... Yesterday I was in the grocery store on base, and I saw a Grandpa playing with his Granddaughter and making her laugh and giggle and tears welled up in my eyes... Just typing it out makes tears in my eyes.. I don't know why I still feel this way and if it will ever end, but I would at least like to talk with other women who have also lost a little one... Thank you in advance for your response and God Bless you all.
