Thanks for all of your input-- it helps a lot =)
i was told that the first day was the red blood, not the brown stuff you get first.
My RE and my OB have different opinions on this---My OB says the first day of heavy flow.....My RE says the first sign of any blood including spotting....UGH!
Yes, your are right candie429. cound day one when you have a heavy flow.
I agree with the above poster. Generally, you count the first day as when it starts to actually "flow".
I believe the rule of thumb is that when you start having bleeding that is heavy enough to require a pad/tampon, then you should count that as day #1.
Hopefully someone else can correct me if I'm wrong!
