I thought I only needed to do that for the external ultrasound but the (scary) woman on the phone insisted I had to do it for this one, too. I'm sure she's right but has anyone else had this done and did you have to drink the water in advance?
Plus, is it a VERY embarrassing procedure or is it OK...?
I'm mostly just worried at the moment that my (highly irregular) period is going to show up about ten minutes before I'm due for the appointment.
