I had results back from the GP after having swabs, I have occurred a vaginal bacterial infection and an STI. I only started with symptoms a month ago. Are these symptoms caused from my bacterial infection or STI? My partner has told me that this happened two and a half years ago- could it stay in my system for this long and only start showing symptoms now- or are these symptoms from my other infection? HELP! If this could have been passed on more recently, I will definitely be walking away from the relationship- but I have no proof and don't know how long I have had this for.
