Post Conization 3 months symptoms

Hi all, I had a successful conization proceedure in the beginning of June. I had some minor complications post proceedure with excessive bleeding and a small infection. Other than that, I healed well.

For the past two months, I have had a dark brown discharge that is a combination of mucus texture and old blood color. I also have a slight itch like I normally would have for a yeast infection. I have treated for a yeast infection with no results. Do you have any idea what this could be? My next follow up appointment isn't until October 19th.
