Vagina smells... help!

So lately my vagina has been smelling really bad... when I get out of the shower it’s fine at first but then this smell by the end of the day is AWFUL. It smells almost like fart. And it’s so strong. I can smell it just walking around at work. I’m super self conscious and I don’t know what to do. I think it might be BV but I’m so scared to go to the doctor... please tell me if this has ever happened to you and what you did to cure it.
