I had unprotected sex with a girl who had no obvious symptoms of herpes. She also claims she doesn't have it, which doesn't mean anything since she's never been tested. This happened about 2 months ago. I never developed any symptoms until maybe 5 weeks after the exposure. I started getting slight balanitis (redness around the ring on the head of my penis). About a week and a half or so later I developed a small bump on the base of my shaft, I poked and prodded at it and it went away within the same day. This bump was accompanied by pain in my right leg. I remember poking at it then going to the clinic to get it checked and when I presented my unit, it was so small that I couldn't find it, but I eventually did (it was maybe 1/4 the size it was originally). Anyways, the next day I developed a small bump on the underside of my shaft that was just plain red. I poked at it and pinched it to see if it would pop but it didn't. It scabbed because I made it bleed (I think, I'm not 100%). I then got ANOTHER bump the next day on the left side of my shaft that when I popped it white pus came out (so i believe it was just a pimple, this has happened before but its insanely rare for me to get a whitehead on my penis). Once that was gone about 2 days later I got another bump at the same location as the pimple which when I popped it, clear liquid came out with a little bit of white, but mostly completely clear liquid. I had weird feelings on my penis for about 3 weeks while this was happening also, like stabbing pains and twitching. Fast forward about another week and another bump pops up where the pimple was, this time I am smarter and decide to watch it without popping it. It shrinks to nothing in maybe 2 days. I should mention none of the bumps have ever itched, tingled, hurt (not even the slightest) or scabbed (maybe because I popped them all), except for the one where I believe only scabbed due to the pinching. All of this happened in the span of 4 weeks, about 4.5 -5 weeks after the possible exposure. I had a herpes IGG at 7.5 weeks which came back negative. I should also mention that I have very dry skin on my penis, which I've now been moisturizing. I also do still have slight balanitis, it was never itched or hurt and is only represented as redness on the rim of my penis. And not matter what, I'm going to get another IGG test at 13 weeks (I would do 12 weeks but I'm insanely busy that week with multiple midterms).
My questions are:
1) Is an IGG reliable at this time given my symptoms?
2) Do these symptoms sound like Herpes? I just don't know what else it could be.
3) Wouldn't the antibodies in my blood be detectable since I had been having symptoms for over 3 weeks before I got tested?
4) If I'm negative at 13 weeks, does that rule out herpes as the cause 100%?
Thanks for taking the time to respond!
