HIV Symptoms or ARS ??

Sorry in advance for the long post, but thanks in advance for the help!

In the recent months I have had unprotected vaginal intercourse with two women who I do not know that well but assume that they have had many, many partners. The first was maybe 2-3 months ago, and the other was 9 days ago (this one says she got tested "like 2 months ago" and was HIV negative).

Starting last Thursday (almost 6 full days from the most recent encounter, and now 4ish days ago) I started to quickly take on flu-like symptoms. Well, I think they are mostly flu-type symptoms, but let me know what you think. I also got a flu shot a few months ago.

-Fever up to ~101.60 degrees (slowly decreased down to 99.5 now)
-MASSIVE leg muscle soreness, even when sitting or lying down (mainly the calves and hamstrings..pain virtually gone now) and some arm muscle pain for a day or so
-Chills when my fever started to rise (when I waited too long to take more Advil)
-Night sweats (like 2-3 times)
-Sore throat (still prevalent)
-Frequent cough

Would this situation raise a concern for ARS or not really? The same night of my last encounter, I also shared drinking cups with a few people as well (drinking games), so maybe I just picked up a common virus doing that.

1) Do they sound more like a simple flu-type virus than anything else
2) Since the symptoms appeared 2-3 months after the first encounter, and only about 6 days after the second encounter, does that put them outside the usual range for ARS to begin (2-4 week is what I've read on here the most).

Also, the intense muscle soreness is gone, I had a night sweat last night but my mother (a nurse) said that that often happens right before your fever breaks. I woke up this morning with no fever and it just came back slightly this evening (99.5 degrees). My sore throat is also partially better. This all just over 4 days after the symptoms began.

THANKS!!!!
