False positive syphilis test?

Anyone else have a false positive syphilis test during pregnancy? I had a positive a couple months ago but the secondary test they did to double check was negative. My dr wants to test me again to make sure but in the back of my mind I’m a little nervous. I haven’t been with anyone other than my husband in over 10 years so it wouldn’t be my indiscretion. My dr says false positives happen somewhat often but in the meantime I’m side eying my husband lol
