Help!

Found out a week ago I'm pregnant this app says I am 6 wks and 6 days... I scheduled an app with my dr to confirm for this coming Monday...Not sure if I did the right thing or not? I'm so new at this and still confused on what to do when it comes to dr app as I do not have a obgyn.. I would like to get an ultrasound already I am so excited and very anxious to see this little miracle! Can someone please help!
