I get UTIs all the time. And I mean, ALL THE TIME.
A urologist told em something I didn't know. Only drink cranberry or use the cranberry caps during the 1st three days on the infection. After that, the acidity can rip apart your bladder and urethra causing more pain. He said 3 days cranberry and after that tons of water.
No need to be embarrassed Sam. It happens to a lot of women. (Men too but not as often because of anatomy)
