What do u think about this situation? Do i have it or not?

I got checked in September for stds for cheating on my man drunk & came out clean. He does know about it. The month after I was shaving my girl part drunk with one of my boyfriends old razors & cut my self. The cut turned into a blister like thing & then i got a 3 more. So I got checked for stds again but it came out clean at this clinic i used to go to. Now i got checked again at this other clinic in april just to be safe & came out clean. Then I go back not for testing & the doctor tells me that she sees on my file that i have herpes. I tell her I don't but then she goes on to explain that the other clinic had tried to contact me the month after they gave me my clean results. I never got any phone calls nor voice mails from them, so how did this happen? Me & my boyfriend had unprotected sex when i had those blisters not knowing if they were herpes or not & after them still throughout all these months. He's gotten checked & he's clean. How is this? IS it true? Can they possibly have made a mistake? I wanna get checked again at a different clinic just to be sure. What do u think i should do? Help Please!!!
