I have put so itchy relieve cream and it has stopped the itching but now i’m discharging clear and very watery discharge (as the picture shows) . I dont’know what it could be someone help

Normal discharge. If it is green or red then its a infection, naturally the vagina performs discharge as a way of cleaning the inside of the vagina.
