I usually spot (brown, and no tampon needed) for 36-48 hours before I start my period. I define the start of my period as when it becomes red and requires a tampon. Does this fit with the official word on when to call it 'Day 1'?
Also, my treatment plan (starting my first treatment cycle in a few weeks) states that Day 1 (when I need to call my FS) is the first day you wake up bleeding. Now this seems like a really silly question, but does that mean that if I start bleeding in the afternoon, that the next day (what I would have called Day 2), is actually Day 1 in FS terms, as it is the first day that I wake up bleeding?
So in the following scenario, would Thursday be 'Day 1'?;
Monday - spotting
Tuesday - spotting
Wednesday - bleeding (afternoon)
Thursday - bleeding
