I just want to sleep

A
So this past week I fall asleep so easy at night but it never fails that come 2-2:30 & 4-4:30 I get up to pee and I'm up for the next hour or more. I just want to sleep a full night again. And no I have not tested yet. AF is due 8/11-8/12!! Could I possibly be pregnant? Other symptoms are heartburn, creamy cm, mild headaches, and craving salt!
