IUD and glow?

I'm just wondering if there is anything I can do to adjust the settings so that glow doesn't say my period is late all the time. I have an IUD and my periods have stopped for the most part, I've put in that I have an IUD for birth control but it just keeps asking if I've had my period yet and says it's late however many days. I'm just wondering what I can do to make things more accurate.

Sorry in advance if this is in the wrong group, but I'm hoping someone else with an IUD can help me out
