Are these HIV symptoms or just chickenpox?

Hi. My suspected exposure was 11 weeks ago. That sex was just so fast because the woman was top on me and I stopped after 4 thrusts because I felt guilt. Lets just say its like 5 to 10 seconds sex. In my 9th week after that exposure, I experienced headache, fever, muscle/joint aches and blisters and red small bumps on my back, chest, face, scalp, legs. I consulted to a doctor and he said its a chickenpox. After 4 days of my consultation, i still feels anxious so I decided to get an HIV test. After 30 minutes I got the result and it is negative. After 2 weeks with my chickenpox, the blisters turned to scabs and feeling better. I know I should get tested again after 90 days from the exposure. Did I get chicken pox or HIV symptoms? image attached is a picture of my back after 1 week!

HiV IS difficult to catch. Belive on doctor.

it is? and if you do catch is it a must to show symptoms within the 2-6 weeks range? or are the symptoms unavoidable because the immune system senses something is wrong

not must. may be. i have heard one case were patient got ti know that he is hiv positive for 20-30 year at age of 70 in final stage.
so symptoms may be there and may bot be. but there is also not set of symptoms which defines that.
