My boyfriend came to me in dec, 2021 and told me that he was contacted by a girl that he was with before we got together that told him that she has syphilis. (at this point we had been together close to 6 months ). So we both got tested he came back positive and I came back non-reactive (btw they were rpr tests). But now I have been experiencing symptoms (a sore in my mouth, and have swollen lympnodes near my lower region), i'm about to order another test to make sure. But my question is what are the odds that after 6 months I didn't have it and he did. Or is it more likely that he was with this other person more recently than he said he was and when I got tested was too soon for it to show that I actually did have it? Please help me with this cuz if I do have it. It doesn't make sense to me of why now I may have it and not have it before. Thank you.
