From the description lrovided it sounds like you could be suffering from an infection (most probably bacterial vaginosis
, yeast/fungal infection
I would advise you to visit a doctor and get your urine analysed along with a vaginal swab test to confirm the diagnosis. Usually your doctor would be able to suspect a diagnosis based just on a physical examination.
Once you are diagnosed, treatment initiated will help in generating an improvement within 24-48 hours.
In the meantime, please abstain from all forms of sexual contact.
Hope this helps.
