Fertile Window is WRONG

Jessica
I don't like how Glow never changes my fertile week. When I take OPKs and I log it as negative, I feel like Glow should shift my fertile week because it makes it look like we aren't having enough BD. I just got my surge test today and I know, based on previous months, I'll probably get at least four-five more positive tests and my fertile window won't reflect that. I know I know I know Glow is simply an estimate, but I just feel like it should change when I log!
