Because of the spotting and bleeding. I had spotted pink sat, then brown, sunday, by the end of the day it was turning red but not bright red. I am the same way today but by late morning no more blood. So I thought I would take one more test to see if it still said pregnant and it didnt it says not pregnant now I have a dr appointment for tomorrow night but I am going to call them after their lunch hr to see if they will take me in tonight. I am so upset and bummed out.
