Issues with Flo app

[Gaga891]

Hi all. Made this account as I can’t seem to find answers anywhere. Ttc after a miscarriage. Have been using the Flo app. For the second month in a row it is moving my period prediction start date. Why is this? I haven’t logged any symptoms or anything into the app.
It initially said period predicted to start on Friday May 18th, when I went into the app on Friday afternoon it had automatically changed the start date to saturday May 19th. Now it has moved it again to sunday May 20th. I’m baffled!
I took about 10 tests last month, and I promised myself I wouldn’t put myself through it again until I was certain my period was late, but now feel I can’t trust the app....

It's because you didn't log your period on the day it was due.

I've only been using it since Feb and up until my period that was due 2 weeks ago (still not shown up), it was pretty accurate at prediction when it would be.

I noticed when I first started using it, it had me on a 28 day cycle and when I didn't get, or log, my period on the day they said it was due, it was pushed back until it did come

Thanks so much responding! So it’s as simple as that!? Why not just mark it as late. So frustrating. I sat with a pen and paper after posting this last night and charted my cycle over the last 3 months since the mc, I’m regular as clockwork and my own workings says I am due on today.....

Hi @Gaga891 it doesnt mark it late until its 2 weeks late i think. Im on cd 60 today and it didnt start saying it was late until cd 40 x
