Usually when women write about the smell associated with BV, it's like a dead, rotten meat smell, especially right after their period. Acidic smell for vaginal discharge is pretty normal. Also so is clear or yellow (or yellow-green) in color. It doesn't really sound like you have BV.
No bacterial vaginosis comes with fishy bad smell odour and it s not yellow in colour , usually what s yellow in colour is trichomonas . So you are taking wrong treatement
I agree with anniebrooke, the hallmark sign of BV is the foul odor. It's distinctive although it can come and go. Do you have itching? It may just be normal without being your norm. Meaning it's just discharge. When in doubt though, see the doctor.
