Implantation?

So I am 10 days late on my period, I had spotting on two occasions and literally I went to the bathroom wiped and there was some spotting And that's all she

Wrote, lol the first time it was like old brown blood and that was when I was 5-6 days late and today I'm 10 days late and I had some very light pink chunky discharge only once this morning when I went to the bathroom and I wiped. I have been cramping very lightly on and off the whole time. I took a test tonight that was negative, shouldn't it have been long enough for the test to show positive with me being so late?
