Late Period, Paraguard

Sierra

I know I should probably get a pregnancy test, and I will. But I just wanted to see if anyone had a similar experience. I just switched to the Paraguard Copper IUD a couple months ago and before that I had the Mirena (my period was non-existent then) So once I was on Paraguard, immediately the bleeding came on and I had long and heavy periods every month on time. I am 100% okay with my period. But now it’s 6 days late and I haven’t had cramps. Worried that it’s not on time, and I can’t be pregnant due to my kidney situation. But I most certainly could be pregnant, but don’t want to be because of my IUD. So my question is has anyone with Paraguard had a similar issue with their period?
