Too early to test ?

This would be my third child but last time I did this was 7 years I guess I'm new've been having some odd symptoms for a week or so sudden onset of bad indigestion...feeling really fatigued all the I am two days late...all I'm getting is a milky white discharge a good amount of it and except for tonight I had a mucous stringy like discharge. My boobs are heavy feeling..achy at times...every time I eat and at various times during the day I feel slightly nauseous...with my first two kids I had no morning sickness just slight nausea like this. I am afraid to test cause of the negative outcome...does anyone have any thoughts ?
