Day 12 of no period - 2 negative tests

Hello,

Day 12 of no period (Aug 31 was the day it was due) I thought I was getting my period yesterday because I had some cramps for about an hour shortly after I went to the bathroom thinking that I had gotten it but it was just discharge light brown and that's it. I haven't had any cramping or symptoms of getting my period.

Has anyone else had this happen? If I don't get my period by day 15 I'll get a blood test to see what is happening.

Any thoughts? Is there hope ?
