Hey!
It's not just pregnant women that can have a UTI without any stinging/burning.

Many people (but in my own experience, mostly the elderly) can have a UTI and not have any associatied stinging or burning, but may have other symptoms eg. cloudy urine, increased confusion, temp, etc.

Cloudy urine can be a symptom of a UTI, or of protein in your urine, or any number of other things - but for you, I would think that it would be either of these, and it would be best it you could get an appointment with a GP to do a urine dipstick.

This will tell you whether there is any protein or leukocytes in your urine, and then you should have an idea of what is going on.

I wouldn't go drinking any ural if you don't have any burning/stinging - it is a urinary alkinaliser, and can help to eliminate the cause of any UTI, but mostly just neutralises the acidity of the urine, so that it doesn't burn/sting. I would wait till you get a definate answer that it is a UTI before you take it.

If you wait for your appointment with the midwife, and it turns out that it is an infection, she won't be able to prescribe antibiotics for you. And it may have gotten a lot worse by then - I have seen a number of people who have been hospitalised because of a UTI that got out of hand and they ended up septic (urosepsis).

If it is protein in your urine, then there is something that they could do for that too - or maybe they just take note of how much it is, and check again at your next appointment, and see if the amount has increased and take action then.

Hope you get it sorted out soon!
