What was your risk? Is this the same encounter you had last November?
You would get an accurate test for gonorrhea and chlamydia at a week, depending on what test you had done. If it was a urine or swab test, that would be accurate.
To get syphilis, you have to have direct contact with a sore, and you wouldn't get that until 10 days, at the minimum, so you are not infectious yet.
If you had a risk for HIV, you would be infectious.
If you are going to keep having encounters that concern you, or have risk, you should really start using condoms to end this anxiety cycle.
