Suddenly a UTI?! Is nuvaring evil?!?!

Emma
I never get sick, (there was a time in my life when I should have had parking reserved for me at my hospital but that's behind me!) super super healthy now, my diet is on point! I drink nothing but water and teas, eat only clean food.....
Suddenly though my boyfriend and I decided BC would be an amazing idea... Nuva ring seemed to be the best option!
About two weeks later..
OWWWEWWWWWWEEEEEE OW!!!
Jesus ow!!!!!!!!! Lord in heaven ow!!!!!!!! 
UTI nightmare! My first one ever????
My only suspects is this new bath bomb (perfumes maybe)
Or the nuvaring?!
Is it common to get this?! Because I can't deal with this!
Also any tips on ridding myself of this UTI is welcome! Very anti doctor, very anti medication, so any tips are welcome :)
