So I'm new to this and I've never tracked my period so when I put in the app when my period started thats "cycle day 1" so when your period ends do you go by the last day you bled or the next day when you haven't been bleeding at all? For example my period started Saturday and yesterday my period wasn't that dark so this morning when I took the tampon out it was clean and I haven't bled at all today so would I put that my period needed yesterday?
