No PMS Symptoms 😍

Courtney
Hello!!
Well I'm supposed to start my period today. Usually the week before my period starts I have extremely tender breasts, cramping and not feeling well. This month I have had none of that. 
We have been TTC since October. I'm hoping this may be a sign I'm pregnant? I'm super tired all the time and have been feeling nausea often. Has anyone else experienced this?
