I think I'm pregnant...brown CM

I'm 6 days late but unable to get a test until later tomorrow so for now I'm searching the web.... I've been having this CM for the past 6 days with light cramping on and off. I just checked my cervix and it's soft and low, also it was only One drop of brown CM than nothing..my finger had milky CM after i checked my cervix. Usually I'm dry before Period could this mean I'm pregnant? Is CM common with early pregnancy?
