Unexplained body Odor

Hello everyone!

I really need help figuring out what’s going on with me. I have impeccable hygiene! But, I smell horrible at all times! Most common odor is of sweaty socks. What’s weird is that my feet don’t smell at all. I can smell the odor around my nose. The crease of my nose to be exact.

The odor would get worse depending on my diet. But, it doesn’t matter what I eat, I smell. The odor is very strong. I don’t consume dairy because the odor would get worse, and I get a fecal/poop/sewage odor.
I’m not sure if these odors are coming from my stomach. I had endoscopy done, perfect oral health, tonsils removed, tmau test was negative. I was positive for Sibo only. No matter what I do, I smell bad, musty. I take 2 showers a day, scrub, use antibacterial soaps etc, nothing helps.
I know is coming from inside of me. I constantly smell like cheese. I don’t have any parasites, fungus or anything else that could be possibly be causing this. I can’t take the embarrassment anymore. People don’t understand that is a health condition, not that I’m a dirty person. My hormones are fine, within range. I have notice that close to my ovulation the odor would decrease somewhat, and very rarely I get one good day where people don’t complaint about the smell. I have narrow it down to be close to my ovulation day. I really don’t know what else to do. I have visited, endocrinologist, ENTs, Gastros, functional doctors, dentists, Obgyns.
