New to this - Have a ??

I stopped my BCP with my last cycle. -
So, now how does this whole counting days thing work ?? Do I begin counting from when AF began ? Or ended ?? And do I count until she shows up again ?? We're not actively TTC yet, but I wanted to give my body some time to adjust before starting so I know I need to start paying attention - Before it was just "OOh, the last pill is gone, AF will be here in a few days ......."
Now I actually have to pay some attention to my body - I've been lurking for a little while and you are all SO Perceptive re: what's going with your bodies, I am completely clueless !!

Any suggestions/advice ? A BOOK I should read ?? Lol
TIA !!

Taking Charge of Your Fertility is the book everyone recommends.

You would begin counting from the first day of AF. Which would be CD1 (cycle day 1)

www.FertilityFriend.com is also a good resource.

I thought that babydust.com was pretty informative. I know nothing about this subject, but I am just beginning to do my research
