New to blogging

Okay so I have no idea exactly how to do a blog... but I'm gonna try :) I'm creating this blog so I can share my pregnancy journey with all my friends and family, especially the ones who are far away back home. We're also going to do a countdown and a little competition to see who can guess the baby's weight, length, and birthday...and there will be a small prize :)., and we'll have an online baby shower...but I'm still working on all the details. Anyways, it's a work in progress :)
