Bladder Infections & WLS/ WOW moment

I think I am starting to get a bladder infection, I wont be able to find out for sure because I dont have insurance but Ive had them before when I was little. I was wondering if WLS can cause more bladder infections? I read that the cause was germs in the large intestines so i didnt know if it had anything to do with WLS Ive been having the urge to pee (even if its just a little). It feels like I am peeing constantly!!!! does anyone have any advice on how to cure a bladder infection without going to the dr? Any advice???

P.S I had 3 people tell me today that I was looking good! Also Ive went from a size 22 to a size 16 (just found that out today lol) Ive lost 75lbs and feel GREAT!!!!! (just my little wow moment today)
