First Ultrasound Today!

Had my first ultrasound today at 7 weeks 6 days. We got to see the baby and hear her (I'm hoping) heartbeat. They also confirmed the due date as Oct 19th. So I'm really excited to have halloween time baby! (: This will be my first pregnancy. I am 24 years old and an office manager for a doctor. Me and my boyfriend have our own house and are settled, but this was not planned. So still really nervous. If anyone has any advice or encouragement I would appreciate any help.
