So I’m using this app and one other to help track my cycles so we can get our BFP. My cycles are 28days and are always on time. My one app said AF should have come on the 22nd. But on Glow as I entered my ovulation tests by photos I had a spike when I thought I should on the 6/7th my CD14 then I got another one that my app read as positive CD20 so glow said I’ll get AF on the first... that’s 7 days late ..

I took a digital pregnancy test 2 days ago but it came up negative...

What is gonna by on?

Please help
