My last period was on august 7. I get my period every 45 days. But I've been cramping for 4 days now and I'm suppose to get my period tomorrow. My breast just started to be sore. I do feel nausea after eating. Normally for me I don't get crapms til the day I get my periods and my breast always hurt a week before my period. And now it's been weird. Could I be pregnant!?? I'm really hoping for a positive.
