First appointment tomorrow!! ๐Ÿ™๐Ÿ˜๐Ÿ‘ถ

Lacie
Tomorrow is my first ultrasound/appointment. I will be 8weeks 3days!! I. Am. Petrified! 
   One) this is my first baby; Two) I am driving myself crazy with worry that something will be wrong; and Three) I have NO idea what kind of questions to ask or what to expect!! 
     Can anyone fill me in, enlighten me, and/or give some words of encouragement?! 
Thank you!
