To test or not to test?

🌷Kierston🌷
I am dying to test. I'm also worried that Im out this month. I was spotting for three days with light cramping then it just disappeared. I have been checking my cervix and it is high soft and closed but I still have left over brown spotting. I'm 10dpo, af is due on the 20th. I'm so sick to my stomach, I'm exhausted, my boobs hurt, and all I want is salty food.
