Yes - I used it briefly 5 or so years ago, lasted about 6-8 weeks on it before I told the dr to take it out. I had put on about 4-5kgs no changes in diet. Once it was removed I went back to normal.
Yeahh I gained 30kg in one year when being on nexplanon, took me a whole year to lose the weight
Its different for everyone, i stayed the same weight it was hard for me to loose my weight untill I took my workouts serious and ate healthy. But then it caused ovarian cyst later down the line with unusual periods.
