REALLY strong vinegar smell😭

Hi so I have an extremely strong vinegar smell coming from my vagina, like sometimes I can smell it through my clothes... a week ago I had sex, and he came inside me, a couple days later I had a fishy smell which after some research I learned was bacterial vaginosis. So I tried a couple of remedies that didn't work until I found that some people had had luck with inserting a vitamin C tablet each night for 2 nights. This solution made the most sense to me so I tried it. It worked! But then I had a more sour smell, at first I thought it was just the left over vitamin C, but it's been 2-3 days now and it's so much worse! Yesterday I tried douching with a baking soda mixture (I know douchig is bad, but that was one of the remedies for cytolytic vaginosis) it worked to get rid of the smell completely for a few hours, but now it's back😪has this happened to anyone, or does anyone have any suggestions other than going to my doc? 😬
