Copper IUD and heavier periods

Using Nova-T copper IUD. Haven't had this before having my IUD put in. Might be a coincidence I guess. Since having the IUD put in I feel very anxious and cry easily/ generally have trouble regulating my emotions for the first 3-4 days around the beginning of my period. During more stressful points in my life I would get insomnia around this time (and only this time) due to anxiety. One night I could not sleep at all, for several (probably ~10 more or less) I could only sleep for 3-4 hours. I would feel paranoid that my partner doesn't love me. My periods have also increased in length from ~5-6 days (including spotting I think) to 9 days (not including spotting) or 12-14 days including spotting. Apart from that no other symptoms, but the emotional changes are difficult.

The worst experience ever and highly disappointed that no one actually says the truth about this apart of people who used it. No doctor says about those secondary effects and it’s criminal.

It worked and I didn’t have to worry. Only issue was my periods were soooooo heavy it made me severely anemic. After about 3-4 years I had to take it out and my periods were lighter and my anemia got better
