I started to have vaginal discharge. I treated it with topical antifungal. I am 32, newly married, sexually active. Had 1 previous sex partner (first husband). My now husband has been tested for SDT prior to our wedding. I was also tested. The only change in my routine is i am taking oral iron 2 tabs once daily, and biotin. What could cause the recurring vaginal discharge (no smell, cheese like appearance, minimal tenderness around the labia, no itching).
