Tested HIV negative at 8 weeks but swollen nodes still persist?

On October 1st 2014, I had unprotected sex with a guy who is a lot older than I am and seemed to be the promiscuous kind.
13-15 Oct - I peed blood and took some Chinese medicine and it was gone.
24 Oct - found swollen lymph node in left groin; I had a one night sweat (24-25 Oct)
31 Oct - went to the doctor and got a urine test (15-20 lymphocytes in urine)
23 Nov - found lymph node in neck and behind left ear (small); also had a one night sweat (23-24 Nov)
24 Nov - went to the doctor again and got a urine test (30-40 lymphocytes in urine); She did tell me not to worry about the nodes because they are too small (about 0.5 cm big)
1 Dec - I caught a cold for about a week (very mild not severe)
4 Dec - took an Hiv test and came back negative
9 Dec - subtle pain throughout the body (chest pain both left and right)
26 Dec - found another lymph node under my jaw

In conclusion, I took the Hiv test at  8 weeks (about 61 days) after possible exposure and came back negative. But I still doubt if I catch HIV. Right now, I don't have any other symptoms aside from the lymph nodes, some muscle twitching/tiredness, and subtle pain throughout the body. I've been so stressed lately as well. How likely would an 8 weeks negative result change after 12 weeks? I took the test in Shanghai(China) and do not know which type of test they performed on my blood.

Without knowing the type of HIV test it's hard to say.   Try to find out.
Odds are it was at least a 2nd generation test.   8 weeks is 99%.  
If it's 4th gen. which it could be, you're in the clear.  Be well.

8 week test is very unlikely to be positive at 12 weeks.
