Hi. I'm 18 years old and my period is late for more than a month now. It was supposed to come 17 October and it is 7 November now and I still have yet to see signs of PMS. I never had sex before, did not gain or lose weight and did not change my eating pattern. I have vaginal white discharge when I wipe, kind of thick sometimes. I had missed periods before in the past, but it will start immediately at the beginning of the next month. I was stressed out and overwhelmed by the exams that I had which began on 5 September and ended on 7 November. I am really anxious and worried about this. Any help or suggestion is appreciated.
