Pregnant ? Or period?

I’m due tommrow for my period but no signs of a period I’ve had pregnancy symptoms, light brown discharge, very thirsty, frequent urge to me, sore boobs/nipples, very emotional,dizziness, and back ache and today I have thick white discharge not really any odor to it. But I took a test today that was the 6 days sooner first response and it came back negative I think. I felt like I seen a vvvvvvfl but it was sooo faint that the camera wouldn’t pick up or it could be line eyes? I’m not exactly sure. ANY ADVICE??? Or similar experience? Help please.
