I felt burning really bad and had this thick discharge

Okay, I am a 19 year old girl with a high sex drive, but wants to have sex with the one I love who lives in MO. So, I masturbate with a hair brush holder and always clean it right after I am done, but for some reason I still had problems.I finger'd myself and take the finger out and tasted it for it to taste like the rubber from the hair brush and has this odd after smell. So, I bathed and made sure there is nothing from the hair brush inside of me that maybe would be causing this, which there was nothing.Then, the next day I felt burning really really bad and had this thick mucusy discharge and I do not agree with the smell either. I am so upset about this and I am wondering could this be BV? I started using Apple Cider, but would like a second opinion. I already went to the Gyn a couple months ago and they said I had no problems and haven't had sex since before I went.Please let me know. I am so worried. My love is supposed to be visiting in 3 weeks.This is so embarrassing.
