Ok this is stupid

So the glow is saying that I am going to start my period tommorrow but I am about 3 weeks late already! Then when I click on the day after tommorrow it says my next period is in 48 days but I start every 30 day ! Sorry tired and confused will someone please make sense of this! And I took a test a week ago and also one a week before that they were both negative but I didn't test positive with my daughter till I was 8 weeks so I have no clue until I'm puking lol
