I'm 21, single got my periods on 16 last month and today is 22 of Aug i.e 6 days delay for my periods. I always used to get it one or 2 days before. And never missed a period since from I got it. I don't know why I am not getting it this time. I'm not pregnant and I am sure for it because never been in a relationship. I even took pregnancy test just to be more sure on 19 aug which was clearly negative. When ever I get my periods I used to feel less blood flow in my legs. This was also been my indication for periods. I'm getting it since from 16 but without periods and even like as always my white discharge has gone like it always used to be before periods since from 16. I even tried ginger water, papaya but to no avail. Please help.
