Hi, I am a 23 year old female. I have a boyfriend but we have not had intercourse, so I am still a virgin. I last got my period on September 1st week, and since then I've missed 2 periods that were due. I am really worried. I went to a doctor last week and she prescribed me Duphaston 10mg. I took it 3 times for 5 days, but I've still not got my period. I have no signs of irritation or any sort of health problem otherwise (no cramping, no spotting). Have a white discharge occasionally. Please tell me what is the reason I've not yet gotten my period.
