I have a question can i get some help???

De

so my period is due the 7th but last night I started spotting when I went pee and wiped it was light like pinkish so I put a pad on. And when I went again my pad had brown spotting on it think it had only been like an hour and a half so I don't think it could of went brown that fast if it was red and when I wiped there was a streak of something stringy like mixed with blood. Since last night no spotting not a sign I keep going to the bathroom and looking and wiping but nothing. I also took a test Wednesday and it was negative so I have no clue if it's eventually my period gonna start or not
