I am 27 years unmarried girl. I have irregular periods since menarche. For the past 3 years ,i have been experiencing vaginal discharge with small amount of blood  about 2 days before my periods start and then my regular period begins. This time, I noticed white vaginal discharge mixed with a small amount of blood for about five days before my period started. After that, my regular period began.However, I also experienced the same blood-stained white discharge about 5 months ago. After 7 days of blood-stained white discharge, my period started. I have also noticed occasional white discharge mixed with streaks of blood that occurs even when it is not related to my menstrual period. Sometimes I feel little pain in left side of stomach. I consulted a gynecologist and she suggested an ultrasound (USG) scan of the abdomen and pelvis. The scan report was normal, no abnormality detected and the doctor prescribed Femizoy syrup and Welfer XT tablets for 3 months. Is everything ok .Please reply
