I have - actually, when I got Implanon the first time, I went in intending to get an IUD, until the doctor asked if I'd heard of the implant.

Thing is, I actually think (and my boyfriends will attest) I'm more stable *with* the hormones (wonky implant end-of-life excepted) than without. That was why I went on the low-dose pills initially, and why I was glad that there was a low-maintenance option with the hormones. Plus, no periods. :)
