Smell

So I been having this problem for a while. So I been having stringy discharge for maybe a month or two and this smell it’s just smell acidly and it’s always I can shower and a hour lately here’s this discharge or a wet discharge kinda. So I changed birth control. Because I thought it was due to that so for the short time I was off birth control I never had this problem until I back on birth control. Have this happen to you before?
