Increased CM & cramping before AF?!

Elizabeth

Going insane waiting to be able to test! AF due next Tuesday and I’m new to this but I know my fertile window ended 5 days ago. Having cramping in my lower abdomen and back for two days along with an increase in my CM which is creamy. And unusual for me. Any other ladies have this as an early pregnancy sign?? Or due for AF roughly the same time as me?
