Period Question

Elizabeth • Mom to two amazing stepdaughters, Due 9/28/19, hoping for a boy 💙

Ok ladies I never thought of it before but now that I am TTC I think I need to know !! Do you consider your period just heavy bleeding days ? Or do you consider it still going even if it’s just a little spotty brown the last 2 days ? Like my first 2 days are heavy , the 3rd day not much , and the last 2 data just very light brown spotting here and there . So would my period be 3 days or 5 days on my tracker . I ask because I ovulated 3 days before this App told me I should . Any help or insight would be greatly appreciated ! Thank you
