morning sickness?

Rebecca
I'm 3 days away from my missed period. Took a hpt and it came up very faint positive. I'm extremely nauseous and have been for a couple days now. Along with breast pain, diarrhea (sorry TMI) and fatigue! Is this all normal this early on?? I don't remember have nausea this early with my other two it was usually around 7w pregnant. I had a miscarriage beginnging of December and never really "felt pregnant" during that pregnancy. So hoping that this is a good sign!
