About a month ago I had unprotected sex with a guy and the day after I started getting yellow runny discharge. For context my discharge is normally clear/white (healthy). I have been having this discharge for about a month after the encounter, and it’s often extremely runny (feels like an excessive amount of discharge compared to my usual). However I went to the doctors and my tests came back negative for every single std (chlamydia, gonorrhea, trich, BV, yeast, etc.)

I don’t have any other symptoms besides the change in color. The smell is mild. Could this be ureaplasma or what could it be? Has anyone else experienced this? It could be a change in PH or something?
