Im having vaginal discharge for past 6 months...Every time its different for different menstrual cycle s...At first amount of vaginal discharge increased..Then it became curdy thick white discharge with itching...Consulted a gynecologist and used keto b cream and candid v  gel ...Also some antifungal tabs..It cured.... After few weeks again discharge started. Then it changed into light yellow ish discharge with thin constitency...Then again thick white discharge always  cover ing  the opening of vagina.....Now its a mixture of thick white discharge and little yellowish discharge and little greenish yellow discharge with sour smell.. Should I need to worry about this? Im not sexually active
