go and get yourself tested hun - it's better to be safe than sorry! UTI's can happen without any of the normal stining but lots of pain in your bladder - depends on what bacteria is causing the infection!

in the meantime, keep hydrated, try some unsweetened cranberry juice, and maybe even get the Ural satchels you can grab from the chemist (and maybe the supermarket).

a couple of months back, i had a UTI start very similarly to what you're describing, and within 12 hours i was peeing so much blood it was like AF (sorry for the TMI) and i was in crippling pain. AB's took a while to kick in, but the doc said if it hadn't improved within 24 hours he'd have put me in hospital on IV AB's and to rehydrate me - don't let it get to that point - it was nasty!!
