Sudden strange armpit odor

About 8 months ago I started having a very strange odor in only my armpits. I've never had body odor before so this is not normal for me. It is a smell that is indescribable, like a chemical earthy moldy smell, and I can smell the heat coming from them if that makes sense. I have tried everything: numerous deodorants, antifungal creams and supplements, probiotics, detox cleanse, I drink plenty of water and exercise 3-5 days a week. I am 130lbs and 5'5" so I am not overweight and consider myself a "healthy person." I have been to the doctor and of course they were of no help. I did get my blood drawn however, and tests were normal although I am not sure exactly what was tested. I am out of options and would appreciate any help please! Thank you!

Ps. This smell is there even after I shower. I can smell it in the shower. I am ruining all of my shirts at this point.
