possible uti?

So we just got back from a 5 day cruise. We were in the pool like two days or so out of the trip, and got in the water in Mexico. Since we got back I noticed when I pee like as I'm finishing or whatever it burns like SO bad. Also I feel like there's been a little more discharge than usual, especially today. (I just got off my period like Monday if that helps). We got back thursday morning and I don't remember if I noticed it that morning or like Wednesday or something. 
Can you get a UTI or yeast infection from pools? 
My future SIL works at a natatorium and she says public pools/hottubs like on a cruise ship or hotels aren't always up to par like they are supposed to be.
