Smelling yourself

Hey everyone, do any of you have any tips/hacks to work out when they are smelling. At home I never can smell myself(only if don’t shower and it’s other body odours I smell not necessarily the TMAU odour). I only really smell things when I’m outside also others tell me they cannot smell it. I guess most people who have TMAU people around us never want to tell you when you smell. Or I’ve had people around me and I know they can smell something and I cannot smell it. I over dose myself with perfume/oud as I’m so paranoid and I am very aware it can make it worst. Even though I can’t tell if it is 😭
