Hello. I'm Female. 12 Days Ago, (during Ovulation) I Had

hello. I'm female. 12 days ago, (during ovulation) I had unprotected sex. about a week ago i experienced some mild cramping and a few flutters in my stomach at nighttime. it's uncomfortable for me to sleep. I have extreme bloating to the point I'm uncomfortable. I have pain in my lower back, along with some nausea. i'm extremely tired and i'm always thirsty. i'm also struggling with a foul smelling discharge off and on for the past year and so i did a 50/50 peroxide douche. the smell has gone for now but i'm still experiencing these flutters and pressure in my lower abdomen. three days ago i had some pinkish orange spotting and today i'm experience light spotting which i never experience. i'm due for my period tomorrow. and took a pregnancy test. it's negative. i'm worried because I've been struggling with bv for about a year every since i've had to get a vacuum procedure done to clear the remains of a miscarriage. I'm terrified that now, i may have pid and the negative test results along with the abdominal pressure, discomfort, spotting, lower pains, nausea, foul smelling discharge may be a result of damage being caused pid. what should i do?
