Hiv symptoms i feel¡!

I have been experiencing excessive bubbles in my urine. It's like if i literally ate soap or drank shampoo. The bubbles are big too. I can even hear the sound as they disolve. Also for 3 mon been sneezing every day. I was never like this. Every day i sneeze. I also get bone or muscular pain in ramdon places. More over,i get a lot of nerves or spasm all over my body. I feel and see parts of my body twitching.
Tested for urine a week ago,everything was normal. 2 1/2 months ago,i didn't have this problem.
Also, i did no have sneezing problems and now i do. 2 1/2 with intestinal problems every day and gas and liquid. 2 1/2 ago. I shook someone's hzand who is hiv positive,i had a cut from a day before on my finger. 6 days later' sneezing'cold,headc,sore throat. 9 days later dhiarrea for 3 days. 2 weeks later,night sweats,white tongue. Testedfor hiv pcr dna 18 days after exposure,negative. Also,naat hiv test 52 days after,negative. Elisa,62 days after,negative. I feel is the window period. Right now i have the symptoms,but undetected. Why do i urnine bubbles excessive ans before i didnt and the urine test was normal and sneezing everyday and intestine problem?? Only hiv can cause these undetactable symptoms. Also ramdon pain in differents parts of the body. But mainly the intestine in which is 90% of your inmune system,plus i sneeze a lot and runny nose like never before. Can u have hiv symptoms and hiv not be detected??? Is this posible???
