I am just starting my 2nd implanon implant, had the last one the full 3 years and loved it so got a new one as soon as it ran out! For me its been a great option as
-I don't get periods except maybe 2/3 days light bleeding a year and with Crohn's periods always meant horrific cramps and diarrhoea too
-it delivers hormone consistently so it doesn't fluctuate hormone much so less mood swings/stress - always a good thing lol!
-avoids the whole issue of malabsorption which is something that worried me a lot with the pill, and also its just there so there risk of forgetting to take a pill - you'd think with Crohn's I'd be good at remembering to take pills by now!
also as I am on methotrexate I wanted a very reliable option as I absolutely cannot risk accidently getting pregnant on that drug.
