I'll join although I may not actually be CD1. I was on depo, had my last shot June 2014. Last period was Dec 2014 but it may have just been withdrawal bleed from bcp. Started having what I think was my first period since dec last month on the 10th, lasted 4 days then stopped for a few then spotting for 5 days at the end of august. Now I have been spotting for 7 days today is heavier but still pretty light for a period. So today would be CD1 if last month was actually AF but I have no way of knowing for sure
