Pregnancy

Lately I’ve been getting heartburns and extreme nausea. I’m supposed to start af. She’s 2 days late but I cramped for 2 days and now it’s mild cramping. I haven’t had any signs of her showing up either but I keep getting these strong heart burns out of no where. Has any one gotten this in the beginning of pregnancy as well??? Also I got egg white CM a couple days ago and it was an increase amount. And my temp spiked to 99.
