“Do I have syphilis? ”

Hello! I’m a 26 year old female with very limited sexual experience. I’ve never had penetrative sex before or to my knowledgeable come in contact with anyone with syphilis. However, after an std check I was told by my primary care doctor that I had/may have syphilis. I took the test again around 3 months later and came back non reactive? How is it possible to test positive but negative? I’m having trouble understanding the test results (see attached) and would love help understanding what’s going on with me.

I also have a small raised bump near my vaginal opening. It painless and looks to be filled with white liquid? Is this syphilis? Or something else? (Please see attached) I don’t have a gynecologist at the moment but plan to get one.

Thank you for your help!
