Smell um .. down there 😬

So I had noticed a weird strong smell down there for a few weeks but no STI, UTI or yeast infection but I was on and off of antibiotics all last year. I just started taking probiotics maybe a month ago and have noticed a drastic change in smell. Now it’s a light smell and gets better day by day. Someone said it was because the antibiotics wiped out my good bacteria too. Anyone else ever had this problem?
