HIV symptoms and anxiety, and advice as I’m driving myself crazy.

Hi,

First i just want to start by saying i have health anxiety at the best of times so this is literally driving me insane. im 41 female and was dating a guy for 6 months who i met online. He had just split up with his partner who he had recently had a baby to and the relationship was stressful for us both.
2 months ago we had vaginal sex once protected once not. then a month ago we had unprotected anal sex (stupid i know) and we split up. He feels because his ex had a baby a few months ago that would habe picked up anything. he initally has refused to do a test but yeaterday reluctantly agreed.

last couple of weeks i have had the following symptoms:

severe headache (i do get chronic migraines)
dizziness
dry mouth
aching knees
cold sore
slight rash on back of one hand
sometimes get like a trembling cold flash/chills feeling.

i have tested negative for chlamydia and ghomorrea, but i havent done hiv as its too soon i believe and partly really scared.

can anyone take the time to chat with me or share info/advice. my anxiety is theough tje roof.
