IUD or just a coincidence?

Since having kids and putting on alot of weight, my libido has just been so low, I had no desire to be touched, kissed, nothing, only had sex like once every 2ish weeks and my partner acted like he was okay but I could see the frustration sometimes, I felt very guilty because I wanted to want it, but couldnt bring myself to.

A couple days ago I had the mirena inserted to help with heavy periods, I'm scared of hormonal bc so I was on copper before but now I just can't stop dreaming about my man.

Last night I came onto him with kissing and heavy petting and I felt so passionate towards him, unfortunately I'm on my period so it didn't go anywhere, then all night I had many dreams about him, now this morning his at work and I'm still daydreaming about him.

The passed couple days I've felt my love for him grow and starting to obsess over him, like when we were first dating, now I just wish I wasn't on my period so I can jump on him!

Could this be the mirena or something else? I have been working out and eating good too for 2-3 months, lost almost 7lbs so far. It really feels like I've stepped out of some darkness I didn't know I was in and its just amplified since having the mirena inserted.

I was leaning towards the mirena helping but whenever I read about it, I just keep seeing the bad side effects to it like weight gain, acne and depression, so I'm not sure if there are even positive effects to it other than helping with periods 😅
