I was scheduled for a pelvic ultrasound. They told me to drink 32 oz of water an hour before my procedure, which I did. I arrived on time, sat there for 45 minutes past my appointment time, holding my pee.
Then the technician comes to get me and says, "You've been sitting here all this time? No one even told me you were here!"
Then, during the procedure, the room was SO cold that I couldn't stop shaking. I asked for a blanket but they didn't have any and just gave me an extra gown, which didn't help at all. If you go there, be sure to take a blanket with you, and be prepared to wait a long time!
