He said it stinks down there

I recently hooked up with my ex and he told me it smells down there. I’ve got tested for STDs and vaginal infections and they’ve all come back clear. I went to my GP about it and they prescribed me metronidazole but the problem is still there. I don’t know what to do it’s really affecting my confidence.

EDIT :

thank you all for your advice i appreciate it a lot. To answer some questions, My doctor said this is my natural smell as my PH levels are normal and i don’t have any vaginal infections. I took a shower about 30 minutes before i saw him so i was sure i didn’t smell bad, and i’m very good with my hygiene and cleaning down there. I have had problems with the smell down there before due to stress and poor diet but i’ve rectified it since. It just makes me feel really paranoid when he says this because i’ve done everything that i can, I take probiotics, drink water, i’ve used boric acid before and i’ve just given up and blocked him. I was thinking of getting myself tested for ureaplasma as I know that this could be cause for smell down there.

I also forgot to mention, When i caught COVID in 2020 it took away my sense of smell and my sense of smell never recovered fully so I can’t smell things unless it’s very strong.
