As the subject says, i think i have TMAU. I know some people will probably tell me to see a GP and get diagnosed, i would rather seek opinions on here first from people who have experienced it first hand

I am a 19 year old girl and the problem started for me when i began puberty at about 10. I have been reading through the forums and some people mention that eggs, meat etc can cause them to smell. Some people also mention a faecal odour. Mine's is different and i think uncommon. My private area smells fishy for about 3 days after i eat any type of fish, could this be TMAU? No matter how much i shower, the smell is still there and it makes me feel really uncomfortable, especially in public. My boyfriend has mentioned that he can smell it even if i am on the other side of the room! Can someone help me and tell me whether it can still be TMAU without other body parts smelling, eating other foods? Any help would be greatly appreciated!
