I am 11 days late for my period... I took 5 tests all neg.... I don't understand... I am scared, what could possibly be wrong... I have never missed a period in my life and I have no symptoms of it coming, my periods have always been normal... this was my first test at 4 days late...

then I had taken 2 cheap ones and they were neg... I'm scared and don't know what to think.. I have an appt with the gyno dec 1st
