Mirena and acne?

I started mirena almost a week ago and since then my face has been breaking out despite my daily skincare regimen, specifically along my jawline and under my chin (despite my daily skincare regimen I started a few weeks before). I suffer from adult acne anyway (almost never under the chin til now) so it's not totally unusual but it is kind of bothersome. I assume this is just a side effect that will go away on its own, but has anyone else experienced this?
