Copper coil (IUD) and headaches

I was having heavier periods

It's so hard finding contraception that doesn't have side effects and I wanted a hormone free form, so opted for copper IUD. Insertion is manageable, with painkillers beforehand. The first period was tough, I invested in a tens machine pad but the cramps were hard, but not worse than the worst period I've had. Second period non existent, literally three days and barely any blood, but third was heavy and lasted for 10 days. I stopped using the coil not because of any of this alone, but because I'm sure the inflammation in my body was making me uncharacteristically anxious. So hard to put my finger on, but since I got it removed it's been a weight off my shoulders. I'm now worrying that hormonal IUD will make me more anxious, and I haven't had it put in yet. It's overall not been too awful- I wouldn't not recomend it but I had it put in for emergency contraception so hoping there is a better solution out there without the anxiety side effects.

I chose to have the copper IUD inserted in January 2023 because I'd had a bad experience previously with the mini pill (mood swings, decreased libido, and vaginal dryness) and I wanted to try a non-hormonal contraception. The process of getting it inserted was one of the most painful things I've ever experienced with severe pain, cramps, and dizziness. The doctor and nurse I had were wonderful and very reassuring, which made the process slightly easier. I would however, highly recommend anyone thinking of getting it to ask for pain relief if it's available. I'm certain it would have made the process much better and less traumatic for me. What followed was 6 months of intense cramping and spotting at random times of the month and extremely painful, heavy, and long (between 10-12 days) periods (I was lucky to have very light periods before going on any contraception which is one of the reasons I opted for the copper IUD). After 6 months or so my periods settled down to become shorter (5-6 days) and more regular but remained extremely heavy with lots of dark blood clots and severe cramping/back pain - to the point where I would have to take days off work and couldn't exercise normally because I felt sick/dizzy from the pain. The severe cramps started like clockwork on the 7th day before my period was due and continued until the end of my period meaning I was having up to two weeks a month of severe cramping. I also experienced cramps and thick, brownish discharge/spotting around ovulation. Other than the heavy, painful periods, I experienced none of the mood swings, weight gain, or loss of libido that I'd experienced on hormonal contraception, so the copper IUD was great for that. If anything, I experienced a notable increase in my libido! I chose to have the IUD removed about two weeks ago, after just over two years, because I was finding it increasingly difficult to cope with the intensely painful cramps and heavy bleeding and I developed severe iron deficiency anemia, likely due to my heavier periods. I was nervous about the removal process after finding the insertion process so difficult but it was significantly less painful and super quick. I had some light spotting afterward and some minor cramps but nothing too bad. I'm yet to have a period after removal and I'm, so far, two days late (confirmed not pregnant). I would normally have had at least a week of intensely painful cramps by now but so far, nothing. Overall, the copper IUD was great at the times of the month I wasn't bleeding or ovulating and I liked not having any of the side effects that come with hormonal birth control, but it ultimately wasn't worth the heavy and painful periods/iron deficiency anemia for me!
