green discharge and vaginal soreness again


hi all,

I recently just took 2 gels/creams prescribed for bacterial vaginosis. everything was fine after I used what my doctor gave me. this last for about 2 or 3 weeks maybe. I just got my period and now suddenly, I’m having green discharge again and vaginal soreness again as well. I’ve changed everything for down there to cotton and fragrance free. I did get tested for any STD’s and they came back as negative. has anyone else had this or know what could possibly be the reason? I plan on calling to see if they can give me something stronger or another round
