I have a copper IUD and I love it. The first couple of periods after getting it inserted were awful - super heavy and clotty - but I'm back to normal now, (5 months in).
I was on the pill for 10 years before deciding to try for our son and had fertility issues as a result of this. I did try the mini pill but didn't like side effects, (zero sex drive, acne).
I also believe that messing around with hormones is probably less than ideal - especially if you have other options.
