Super long cycle Copper IUD

Jordan

Little back story, i am nearly 9 months postpartum, I got my copper IUD inserted in August around 6 months postpartum. I've had normal on time periods/cycles since 6 weeks postpartum.

I am currently on CD40. And no signs of period. I am sexually active and terrified that the IUD has failed. I'm going to give it a couple more days and then test. According to the app I'm 8 days late now.

Has anyone had abnormally long cycles with the copper IUD? I know that the common side effects are heavy bleeding and cramps but I only got slightly more intense cramps.

Ugh any advice or opinions? Thanks 😬
