Pms or Pregnancy?

Sara

I know it's too early to tell but I'm getting anxious.

AF is due next week.

Symptoms are::

boobs hurt

nausea

lower abdominal cramping on n off (none today only yesterday)

fatigue

bad heartburn

My husband keeps saying I'm pregnant everytime I don't feel well or heartburn is kicking my ass. I really hope he's right!
