Freaking out!

Hey ladies,
I recently found out I am carrying my rainbow baby. I got to see the little bugger moving around in the ultrasound and see and hear the heartbeat. I was prepared for no baby again. 
So now.... I'm freaking out! I am so excited but I keep thinking to myself "girl you are not ready!"  Is anybody else feeling not ready?! I know my fiancé and I will be great parents but these hormones have me crying over the silliest things!
