Hi, my period was supposed to start 6 days ago

Patient: Hi, my period was supposed to start 6 days ago. The day it was supposed to start I had a very light spotting, not even worth putting a tampon in. No period or spotting after that. For the last 3-4 days I have noticed a pinkish orange discharge with no odor and only after going to the washroom and wiping. I have taken two at home pregnancy tests within the last two weeks but both came back negative. Could this still be pregnancy?

Symptoms: Pink-orange discharge with no odor
Mild cramping in lower abdomen
Headaches
