IUD bleeding

Hey girlys I’ve had my iud since November 2022 it’s been 1 year and 5 months my periods have been the same since I got it but this year so far I get my normal mood swings around the time of my period but I only bleed lightly and it’s always around my periods due date so am I in the period where my periods have slowed down and are gonna soon end or what? Last period to be safe I took a pregnancy test it was negative but I’m not worried about pregnancy just want to learn about my new cycle new flow and iud a little more so please share stories and help me :)
