I meant to say "a culture test is the next best option."
No, it does not sound like herpes. Without obvious blisters, lesions and sores, it is not herpes. If herpes is your only concern, save the money and do not go to a doctor or urgent care. Is you get blisters, lesions, or sores, then immediately see a medical professional, get them swabbed and PCR tested or cultured. PCR testing is the preferred method, but if you do not have access to PCR testing, then swabbing is the next best thing.
I would strongly encourage you to get in the habit of using condoms with partners of unknown STD status. Herpes should be the least of your concerns when having unprotected sex with random partners. There are far more damaging STD's than herpes to be caught, including HIV, gonorrhea, chlamydia and syphilis. These STDs can be asymptomatic or go unnoticed and by the time you actually get a diagnosis, these STDs can inflict a lot of damage on your health.
The odds you caught herpes from this one episode of unprotected sex are very low. Somewhere probably in the 1 in 1,000 range. You probably do not even need testing, but if you want more assurance, go ahead and get IgG tested. 12 weeks is long enough. If you caught herpes, you would've have more than likely already had very obvious symptoms and a positive antibody test. The chances of neither to have happened by 10-12 weeks is extremely remote.
Doesn’t sound like hsv as they don’t change and then go away and come back. Still, when you see/feel them, go to a doctor or an urgent care right away to have them looked at.
Doesn’t sound troublesome but please still have them looked at.
