First sonogram bumped 1 week! Booo..

I am about 9w4d pregnant (give or take) and today was supposed to be my first doctor's visit with a sonogram. My husband and I got to the office and they didn't have my appointment. After further digging they determined they just put the wrong patient name in my appointment time so I technically was on the schedule... only the doctor wasn't in because he was at the hospital delivering a baby. Because they had the wrong name down we didn't get the message that all appointments were cancelled. I get that it is the nature of the business to have this happen (I'm sure I caused appt cancellations when I had my first), I am just bummed I have to wait another week to get this appt in (leaving work early, etc). I know, I know.. first world problems... I'm just feeling selfish and petty.. don't worry, I was still outwardly kind and understanding to the office staff.
