Tmi spotting question

Brooke

My period is supposed to start in 4 days. I took a pregnancy test this morning and got a pretty discouraging negative. Went pee this afternoon and had some bright pink spotting when I wiped but nothing in my underwear a half hour later had to pee again this time this spotting was less but brown. Then about an hour after that went pee again no spotting it was gone I feel like my periods messing with me HELP!!!
