White/yellow discharge

Emily

It’s been about a week and a half since I’ve had unprotected sex. I’ve had the symptoms of a yeast infection since Sunday but when I went and got tested today there was no sign of a yeast infection or any type of STD or infection. I’ve had a ton of white discharge (odorless) thay just started getting a tinge of yellow in it today (again odorless) and when I say a ton I mean it’s enough to cover my underwear. I’m so confused as to what’s going on.. has anyone experienced this before?
