No STDs. Then why the odor?!!!!!

So I’ve been suffering for a while now with vaginal odor. I recently started to have a lot more discharge than usual so I ended up going to the doctors because I thought I had chlamydia which I had once before and I was having those symptoms. Well the tests came back negative which means I have no stds and I also don’t have any bacterial or yeast infections. So why am I having this odor and discharge. When I wash my vaginal area I don’t wash with soap I rinse with warm water and scrub with a face cloth. I shower every morning. I just don’t understand and it is making me so insecure about myself to the point I don’t even want to have sex with my fiancé 😔
