Period Logging?

This is my first time tracking my ovulation. My husband and I are trying for our 2nd child. I'm trying to wrap my head around all of the logging and the bbt and CM. I'm just confused as to when I should stop logging my period. When active bleeding stops? Or when I'm done shedding the stringy, dark lining at the end? I feel like every day I'm having to edit my log to add an extra day because I'm not done shedding. Do I log the shedding or just the bright blood? Sorry of it is TMI. But thank you to anyone who responds!
