Take a deep breath my man. Your yellow tongue is most likely the result of anxiety. The doc here says a 6-8 week negative test is conclusive. Throw in that negative PCR and its a cinch.
I was in your exact same position a couple of months ago. I'm getting married soon too. I was overwhelmed with the thought that I had thrown everything away. The odds are astronomically in your favor.
The symptoms that you feel are almost definitely the product of anxiety and guilt.
I had it all. I still have a white tongue. I had diarrhea, swollen lymph nodes, head aches, coughing, night sweats, fatigue, complete inablity to concentrate. I am negative though. Symptoms mean nothing.
Stop looking for symptoms and your life will improve drastically. I promise you that. If you look for symptoms, you will find them. Once you find them, your anxiety will increase. Your anxiety will bring more symptoms...and so on.
In my armpits, there are some red spots...theses spots appeared before my sexual contact. So, I don't concern abou them. And I have still red or brown somethings in my armpits.
I am wondering is this YELLOW tongue is a HIV symptoms?
Your symptoms have nothing to do with HIV, you never had a risk to begin with, you used a condom and you are safe, relate every thing to anxiety, HIV is not the problem here.
