Soooo Confused

Savannah
Okay So Glow At First Said My AF Was Due Oct. 24th It Didn't Show I Downloaded Another App As Well And It Said AF Was Due Oct. 27th Still A No Show I Tested The 22nd But It Was A BFN Should I Test Again If It Doesn't Show Up By Friday. I Don't Know If It's Due To Being On Depo For 2 Years Straight And They Just Aren't Regulated Yet Or What Just Very Confused ?
