Quoting snglemama:" how did you get rid of a bladder infection without antibiotics? yeast infections... you can get them ... [snip!] ... get them any time. Yes, more common during pregnancy.. but that doesnt' mean you're pregnant. if you're worried.. take a test"
There are a LOT of homeopathic/naturepathic remedies for UTIs. As long as you catch it early you can totally treat it at home.
The bad thing about antibiotics, is if you take them all the time, they get less and less and less effective, so you need stronger and stronger and stronger medications. If you treat with natural remedies instead, your body is more likely to respond to antibiotics when you DO actually NEED them.
