where are my symptoms?

6 weeks along and still no symptoms.  Some pain in the uterine area (I'm hoping that's from stretching ligaments), and a little tired.  But no morning sickness, no nausea, no tender breasts....it really scares me.  I was hoping this time around I would feel a little nauseaus....it would put my mind a little at ease if I actually felt pregnant. :(  This makes me think that once again things are not right, and that I'm headed again down a bad road.  I just keep on praying...
