Trouble collecting urine

CarWalsh17

This is so embarrassing, but I would love to know if anyone else has the same problem as me.  Every time I have to provide urine for collection, no matter how badly I need to go, I can't seem to get enough!  My doctor's office said the small sample I've been providing before all visits is just enough, but if I need to provide more for a clean catch/culture, I can't seem to get enough.  I had to re-do a clean catch today because the last one came back contaminated, and I definitely don't think I provided enough.  They will call me for a re-do if necessary.

Does anyone have any tips for relaxing?  I'm desperate!  I don't want to have to worry about this every time I go to the doctor.

Thanks in advance!
