Welcome to the forum. Bottom line: for sure you do not have HIV. Something else is responsible for your symptoms.
Why am I so sure? First, you had a low risk exposure; unless your partner was at particularly high risk for HIV (gay or bi, injection drug user, etc) it is very unlikely he has HIV; and if he did, the average transmission risk for vaginal sex, male to female, is around once for every 1,000 exposures.
Second, your symptoms really don't sound at all like a new HIV infection. Most symptoms that occur with almost any infection also occur with HIV, and some of your individual symptoms could go along with that. However, the pattern of symptoms you describe doesn't sound like HIV. Absence of high fever also is good evidence against HIV, regardless of other symptoms.
Finally and most important, the HIV tests never lie, as long as testing is done sufficiently long after the last possible exposure -- and with modern HIV tests, that time is almost never longer than 6 weeks. Therefore, test results always overrule symptoms (no matter how typical for HIV) and exposure history (no matter how high risk it was). Your first negative test result at 8 weeks proved you weren't infected and the later ones confirm it. Because some experts continue to advise testing at 3 months (12-13 weeks), you might want to have a final test at that time -- but there is no chance it will be positive.
I hope this information is helpful. Really, you can stop worrying about HIV. If any symptoms continue or otherwise concern you, continue to work with your personal health care provider about the problem.

Sorry, I cannot help further. You have heard the facts and very reasoned reassurance. Your continued fear is emotional, probably related to a sexual encounter you regret, and not likely to go away by hearing the facts once again. I'll just say again that for sure you do not have HIV. I suggest you re-read all my comments above and concentrate on them carefully. If your fears continue despite doing that, I recommend professional counseling. I doubt your fears will resolve until you do that. I suggest it out of compassion, not criticism.
In any case, there is nothing more this forum can offer you, so that will have to end this thread. I won't have any further comments.
You have given me a lot of reassurance.. However I can't help it, I am still terrified. I can't shake it. In the reasoning in my head, I think that since my diarrhea and joint pain stopped so abruptly that that signaled that seroconversion was complete.. that for some reason my acute symptoms lasted that long and that now I am going to test positive. Friday marks 12 weeks. So CAN symptoms last ten weeks or more? Also wondering if symptoms could last only one to two days.
You're welcome; glad to have helped.
The only HIV tests on the market in the US are the modern, accurate ones. It dosn't matter where you live; you can't get a bad one.
Thank you so much for your prompt reply. What worries me is that I live in a very small town. What if they don't have the most up to date testing?
I saw these comments and took them into account in my reply above.
Forgot a couple things... in the beginning I constantly felt as though I had a UTI, but I didn't. At one point I had to really push to urinate. Also, I've been sweating a lot and my skin always feels clammy when I do. Cold sweats, I guess? And I get this rash under my chin that comes and goes, usually when I am doint something active.
