T.M.I …….. HELP

Nina

So I had slept with a guy who claimed he had been tested and clean…… I had met him through a friend and trusted the idea ( stupid choice) …… it’s been 7 days and around 4 days after I slept with him I started getting yeast infection symptoms, I had gone to the dr 5 days after intercourse and they took a urine sample , proscribed me a yeast infection pill and let me go, I had taken the antibiotic but the next morning had gotten green discharge….. I thought maybe my body is detoxing the infection but had shown a family member the discharge for another opinion. The family member had said she thinks it’s an std . I immediately freaked out and made an appointment but the next available appointment was not for two days , does anyone know any home treatments that I can use to hold over and possibly help clear whatever infection I have ….. any advice would be appreciated.
