hallo and thank you for asking HCM, I understand your concern but there is no fear for HIV infection if you did the test 8 times in a two year period. You haven t mentioned what kind of health problems you have, therefore I can t say which other conditions could be the reason of your symptoms. But sometimes, people who are affraid of getting some disease develop symptomes without any real cause, it s called psychomatic. My suggestion is to visit an infectologist, who is a specialist for HIV and AIDS, to seee if your health problems could be connected with some other STD 8sexually transmitted disease). Until than try to avoid sexual activity without protection. I hope this answer was helpful to you.
