You didn’t mention if the sex was protected. A condom offers great protection. Not fail safe but good.
Did you get the bump swabbed? If the bumper. In the past few days, you could still go back to the clinic and ask for a swab. Swabs are the most accurate. Since it sounds like you had a blood test, you want to confirm that it was an IgG test. Those are most accurate for HSV two after 12 weeks since exposure. It can miss a very small percentage of infections. You need to know for sure what test was performed. Also note, that an IgG test this is up to 30% of HSV one infections. So if you received oral sex during these encounters, you could also get HSV one genitally. I cannot offer any advice on the lab or techniques used in Puerto Rico. I assume they are comparable to the testing here in the states. Confirm what test was performed and if any further bumps appear, have them swabbed
