I don't know....Good question!
Thanks...I called and they said to call back when its flow not to count spotting. I wonder why some doctors are so different...makes me question weather what is right.
I would call too cause my Re says anything as day 1, good luck,
My RE does not count spotting, but when the full flow comes, but I would say you are better off calling them now to be on the safe side!
My RE always told me to count when I start my cycle, no matter how light it is, as day 1. I would call them and tell them exactly what you typed. They can let you know for sure... but you don't want to miss you window of opportunity, just in case they are like my RE.
