Diff apps, diff fertile windows

I have like all the apps almost and honestly I think all of these apps are just more of a job putting everything into every single one of them sucks and as I’m here tonight trying to see if I passed my O or wondering has it even happened yet and of course with my luck I ran out of opks on 2/9 Bc I was sure I’d be O by then since the CM was there

So here are all the apps with the estimated fertile window it gave me and what doesn’t make sense is that all are set on 32cds and I make sure to log the exact same thing in each and every one so why the 💆🏼‍♀️💆🏼‍♀️💆🏼‍♀️💆🏼‍♀️ are they different!!?

Glow 2/6-2/12

Ovia 2/9-2/14

Flo 2/1-2/11

Then frer online tool 2/6-2/10

Neg opks on 2/4,2/6,2/8, 😭 then 2/9 progressed darker but still lighter than the control 😕 then I ran out of opks 🤦🏼‍♀️

I’ve been sticking with this app mainly for the community but annoying times like this(on top of having multiple apps) I’m starting to think I should just stop trying to track and live life in hopes that it will take some stress off of trying and making bding a chore.

ACTUALLY yes that is what I will do
