I've used vaginal medication but the burning wont stop?

Ok so I went to the doctor months ago after suffering with the itching, and burning…etc. I was told that I had BV, so I got the perscribed medicine and it went away for a while but now its back. I got the book called how to cure BV in three days and began doing the steps with the Hyrodrogen Peroixide and Vaginal capsules. At first the odor went away, and not too much itching, but a liquid was coming out every day I assumed it was from the vaginal inserts. On the third day I saw more white foam from the hyrodgen peroixide. That day I had more burning and itching censation, so I did it one more day then stopped. I continued to use the vaginal inserts every night because that’s what the instructions said. After continued irritation I stopped using them. So still suffering from burning and itching I bought a yeast infection kit because I thought maybe that’s what it is. Well after using it Im still burning and irritable, I dont know what I have done to myself but the burning has not gone away all day today, can anyone help me or have experienced anything like this?
