No doctor can ever predict if you will turn positive for HIV
infection after 6 months. Please relax; it seems like you had viral fever
. As said by your doctor, repeat the test after 6 months. If you are negative then you are negative. But, you can turn out to be HIV positive, if you have an exposure in the coming days.
So, practice safe sex
, be vigilant in case you take any blood transfusions. Always have protected sexual intercourse.
Hope this helps you.
All the best.
