Im late after IUD removal

Lilly

I have a 2 days late period today after IUD copper removal last month at the 11th which was days before I was supposed to ovulate. I have done three test on Friday Saturday and Sunday. (BFN) I am confused and stressed. My period was on May 14 I got my IUD on the 16th and again got a period on June 4th. I hated it and took it out.
