ok. so im 19 and i have been having this extreme yellowish/greensih discharge.the way it looks is of something that reminds me of boogers. its been happening since the last time i had sex about 2 months ago. it was itching very bad at first and then it stopped. now its just the uncomfortable discharge.it is constantly happening. i change my underwear multiple times a day because it goes through. it is worse over night when im sleeping though. when i wake up in the morning it sometimes goes through my pants. it smells kinda bad but mostly if i dont change soon enough. i set up an appointment for next month but im super embbarrased to go because it is so nasty. does anyone know whats going on, and how serious it could be. it is really ruining my life. please help
