Implantation BBT dip

Brittany
I read that during implantation your bbt will have a dramatic low point and rise and stay elevated.  do you think that's what this could be?  It might sound crazy but I think I'm feeling symptoms already.  I've felt nauseous and super tired and I felt cramps in an unusual spot for me.  It was right where my uterus is.  Am I crazy and getting my hopes up?
