Mucker I know this is after the fact but when I had my second child I had a catheter in the hospital. When I left I could not pee for hours. They were going to re-admit me. The doctor told me to try while in the shower. Sounds gross but she said your own urine is sterile. After about 8 hours without going, I just told everyone, see you, I'm going to take a shower. It worked! Better then a catheter in the hospital! Just had to wash the shower after! No big deal!
