Mirena IUD and headaches

Just got this inserted early November. It's December and Im experiencing a month of bleeding, cramps, irritability, nausea, headaches, dizziness, feeling unwell everyday.

Side effects: cystic acne & overall acne, metallic vaginal discharge, low libido & irritability. It was difficult to tell if IUD was in place since the doctor cut the strings too short. Went into OB & Planned Parenthood, they couldn't find it and were unsure if it fell out. This didn't give me a great deal of security as a BC since I couldn't tell if it was there or not...

I’m sort of neutral about this birth control. I have had years of trying to find an oral hormonal contraceptive that both helped with my excruciating cramps and didn’t make my mood terrible most of the month. I will say, this has stopped my periods most months so I’m not getting cramping nearly as often, however I would say they’re actually worse than before the mirena when I do get them, so sort of win some lose some. It doesn’t affect my mood though, which is nice to not feel dreary all the time. I have gotten a lot of migraines, which is something I ran i to with a couple different pills I tried in the past, so I knew that was a risk of anything that was hormonal. Sometimes OTC pain killers do the trick, but I almost traded the cramps for headaches. I also have never been someone that sweats much, and I live in Arizona, but since getting this I have horrible night sweats and have phases each month where I’m running hot all day and sweating way more than usual. I’ve never had this side effect from a birth control, so that one was unexpected but definitely manageable. With the convenience of not having to take pills in mind, I would say I prefer the IUD to any birth control I have tried so far, but I’m not sure I love the mirena brand itself.
