When women have cloudy urine on the day of ovulation, it is usually not because the urine itself is cloudy, but because of excessive vaginal secretions during ovulation and leucorrhoea, which is not easy to clean, and the vaginal secretions will mix into the urine when urinating, making the urine look cloudy. If you do not have these symptoms, you can wait until after the day of ovulation to observe whether there is cloudy urine. If you still have cloudy urine after the day of ovulation and have symptoms such as frequent and urgent urination, you should have a urinary tract infection and need to drink more water, check the urine routine and take medication if necessary. You need to clean your vulva and take a mid-stage urine for the test.
