New & confused!

Yay! This website is so fun and informative. I am a mommy of 2 (almost 2 and 4) and trying to conceive number three with their step dad who will be my husband in less than two months. When I say trying to conceive I really mean not preventing.

Now that I have introduced myself can somebody explain to me all of the acronyms on this website...specifically the message boards!? I have been able to decipher a few but most are lost on me. Thanks!
