Copper iud is messing with my moods!?!!

I’ve been on the copper iud for a month now. I chose this because of the no hormones. Spotted for not even 5 hours and spotted the other day and that’s it! But the last few weeks I feel off. I thought I was about to start my period cause my hormones go haywire and I’m pretty much an emotional mess. These last few weeks have felt like that. Especially this last week. I just feel sad and like I’m just here. Hopeless and I’ve been picking fights with people. Which is unlike me. I just feel so angry and sad. Disconnected. I read up on the iud I have and I guess the copper can affect this?! Is this true or am I just losing my mind. It’s like that constant pms feeling and I’m emotionally exhausted. I don’t think it’s due to the fact of my baby. I have a 4 year old and a 3 month old and that’s great! He’s a good baby. I however am losing my hair on top of that but it’s okay 😅 anyone else experience these side effects from the iud or am I just losing my shit.
