Hoping for a miracle

I've been trying to get pregnant for the last 3 years nothing YET :( my period was suppose to come down on the 24th of December it's never late today is January 2nd still no period my boobs feel sore I feel a bit fatigue feel a little nausea. I'm really hoping my period doesn't come down & im pregnant fingers crossed ! I feel like I'll never get the chance to become pregnant it's devasting to me :(
