Are these symptoms 😔

Had sex 4 weeks ago without protection vaginal and anal he didnt cum or anything near but i instantly went into panic mode i began to have headaches maybe 2-3 days later that was constant i had no relief they were really mild maybe a 2 out of 10 then maybe 7 on my worse days then my shoulder and neck began to hurt after my head stopped hurting now i have a small lump on the side of my neck i know its a lymph node and im so afraid it could be HIV!

go get tested since it was 2-3 weeks ago the 4th antigen would be accurate
