Copper IUD and I think my period is late?

UPDATE! ** Negative pregnancy test yesterday, and started my period during sex on white sheets today 😬, happy girl😋**

So. I have had the copper IUD since September, and have had a consistent period cycle since then. No issues at all! Well almost three weeks ago I got a new phone, and I couldn’t figure out how to long back into this app, so I don’t remember when my last period was (had to make a new account🙄). I depend heavily on this app to let me know my cycle, and I feel like I should have started by now😬.

I also moved 2 months ago so I don't have a gyno here yet, and the doctor who implanted it is four hours away....

Do any of y'all have experiences of late periods with the copper IUD?

FYI: married and sexually active 😋
