Jessica,
You are not a baby...............I am the whiner and the baby when it comes to having to go for procedures as I stress out ahead of time and feel sick driving to the medical center and then the procedure goes well.
They should let you bring in the first morning sample of urine in a speci cup and then have you not void anymore..............makes more sense to me but they must have a reason.
I will be thinking of you and praying all goes well for you. Let us know when you can how you are.
I have found that I come to this site and post when I am waiting for the time to arrive to go to Dr. appointments as it takes my mind of the worry.
Hugs to you sweetie and good luck.
Kitt
