Hi,
Welcome to ehealthforum,
If symptoms are persistent, consider getting culture sensitivity tests done on the vaginal discharge. Since you are sexually active, get your partner also treated simultaneously to prevent re-infection and avoid having intercourse while both are on treatment. Drink plenty of water. Avoid vaginal douching, use of harsh soap or perfumes in the area (vagina has its own mechanism of cleaning itself. Use of these products harms the normal bacteria of vagina and it becomes susceptible to infection). Use loose cotton undergarments and avoid tight fitting clothes. Also consider getting a PAP smear test done to rule out cervical erosion, dysplasia etc. Hormonal tests done will rule out hormonal issues for the abnormal bleeding.
Take care.
