Needing advice on possible pregnancy symptoms!!!

OK so I am 2 weeks late. AF should have visited on Feb. 23rd. I had some light pink discharge (only about a teaspoon amount) on the day after I was to start, but nothing since. I feel bloated constantly, have very tender breasts, light cramping, nausea and fatigue. I have taken HPT every three days with negative results. Also my CM is really dry which causes some discomfort. Please let me know what you all think. Should I wait longer and take another HPT or should I see the doctor. And could something else be causing pregnancy type symptoms?
