What is going on!???

Hey ladies! I'm 10days late and having all symtoms of pregnancy. Im bloated , cramping, have to pee constantly, craving foods I don't normally eat, headaches, and weirdly severely swollen ankles.i have tested continuously but keep getting a negative. My husband and i are getting frustrated just not knowing at all. I fear going to the doctor will result in another negative test. What should I do? Could I still be pregnant? this will also be my second pregnancy. I found out I was pregnant at 10 weeks with my son.
