Period is late and feeling symptoms

I am 6 days late. Feeling mild cramping in my uterus almost as if I had butterflies in there. My breasts have grown and are slightly sore which they do before my period but they go down when I start. They are still here and feel heavy. I'm fatigued and experiencing leukorrhea. Is it too early to test or should I wait? There is still no signs of a period and I've had these symptoms for 6 days
