Advice...etc?

Ok... so no particular question. I am 22, just married and just found out that I am pregnant!! I am so excited. We have decided to wait a little while before announcing to family and friends so I wanted to tell someone... this is as close as I could get (sad I know) Just wondering if there's anyone out there in the same boat who might want to chat or if anyone has advice on how to relax as I am petrified of miscarrying... Thanx
