Smelly vulva but vag is fine

[Vagwoes]

Since last night I've noticed an unpleasant fishy smell from my labia/vulva. It's not overpowering but I noticed it when I wiped yesterday. No rash or anything like that.
No smell from my actual vagina and discharge etc is normal.
Everything I Google says BV but I thought that was only if the smell was in your vagina, not just the outside?

Any advice or ideas is appreciated.

Hi op, I’d get some swabs done with your GP or local clinic just to rule out anything. If it’s BV it will come back on the swabs
