HELP! I have a UTI

Elizabeth
Okay so I've had a UTI for the past week or two and I've been drinking water non stop, wearing cotton panties, and keeping everything down there clean and nothing is working. I've bought a offbrand AZO and taken them all I'm in pain and uncomfortable. Every time I pee if feels like my whole uterus is going to fall out. Any advice? I don't have insurance ATM so if I go to the doctor it'll be the ER unfortunately..
