5-6 DPO, help pregnant ladies!

Heather • TTC baby number one! Married and both anxious!
I am about 5-6DPO. I have PCOS so it's still a possibility I am farther along. I have having cramping in my lower lower abdomen and white chalky discharge. These are pregnancy symptoms. Has anyone else had this? 
Also, I'm so hungry all the time! 
No other symptoms.
