Hello- am going crazy- I am 3 days late and spotting- very little light brown discharge- not enough to need a tampon or use a whole pad, but would stain knickers. For the last 3 days (including today) or has been like this.. I did a test on day of AF and the missed day - both were negative. I did in the afternoon- potentially could have been diluted - but maybe not as didnt even get a faint line. Has anybody else experienced this and what does it mean? Usually AF starts with brown the same day it goes red and creates a whole flow. Anyone who has been in same boat and could shed some light (I know we are all different). Thank you in advance!
