i had to have a medical for a job i went for and the nurse did a urine sample which showed i has white cells in my wee. she said i had to go to get antibiotics from my docbecause i had a urine infection. But the doc who carried out the medical said it wasnt a concern, especially as i had no knowlege and was not having any unpleasant symptoms.
I wouldnt worry hun, just that you may have a slight infection and not even know it.
