Hey there!

I would say you have a UTI - dehydration would cause your urine to go darker, but not make it appear cloudy. And I have seen many people (mostly older ones though) be admitted to hospital due to a UTI that showed no symptoms at all. Until they got septic from it anyway...

A bit extreme and OT (and this is the first time I've heard of it happening from a UTI, so don't freak out, and thnk it could happen to you), but did you see how some Brazilian (I think) Miss World contestant lost her hands and feet recently (i saw it on ninemsn yesterday), because she had a UTI that got really bad, and into her blood system, and shut down the circulation in her hands and feet, and she had to have them amputated? But yeah, very unlikely that would happen to you, just sharing a story!

So yeah, I reckon it sounds like a UTI - you can go to either your GP or midwife to get it checked out for you.
