I think I might still have a chance ladies! TMI but I had a negative 2 days ago but 2 days ago I started having brown discharge and then the next day it was very very light pink then I had spotted red today and then it stopped! I thought I was gonna start but I usually do on the second day and I'm usually super heavy by the third day this is very unusual for me. Does any one have any thoughts?
