Confused

Does anyone use Glow and Ovia? It seems like my cycles are about 32 days long and glow days my period will start on the 12th but Ovia says it was supposed to start yesterday. Yesterday was 32 days from the beginning of my last period but I ovulated on 9/28 so technically the end of my tww is the 12th. What do y'all think? No signs of af yet but got a bfn this morning. Should I go by the 12th even though I normally would have started my period yesterday?
