For some reason when i urinate it starts off normal but then when the pee starts to completely drain from my bladder i get this horrible sharp aching pain in my left side and as i urinated more and more throughout the day it got worse by the pain lasting longer after i peed, going round my hip and the the last time I peed it started up on the right side as well, is also hurts when i prod my right side where the pain is coming from. This all started a week back but not when i urinated it just hurt for a slight second when i sat down or something. But today it got much worse when i peed and it hurt. I'm not sure weather this may be linked with me having unprotected sex with my boyfriend and I did miss my period, i have been peeing alot more also?
