Hello I had gone through your question very diligently and I can appreciate your concern I see patients with similar complaints in my clinic routinely And I will definitely help you as well in best possible way Looking at your history this could be due to Infection like yeast infection, STI or cervicitis or bacterial vaginosis In my opinion you should consult a gynaecologist for examination and a battery of tests like blood for hemoglobin, CBC ESR ,urine culture and sensitivity test and a vaginal swab for culture as well as KOH fixation test You may require a course of antibiotics or antifungal vaginal pessaries under supervision of your doctor meanwhile maintain good hygiene Have plenty of fluids thanks for your question Best wishes
