Ok ladies!!! Has anyone had irregular periods on a cooper iud? I got my iud inserted in June and my normal on time cycles for both June and July. But this month I’m now a week late. Took a pregnancy test after two days late which was negative and also called my dr this morning who didn’t seem to concerned. But I though with copper iuds that they won’t take your cycle away or have much change. I have heard of heavier periods with the iud has that was also the case with my mirena... HELP!!
