Hi I'm On The IUD Birth Control Called Skyla, I'm

Hi I'm on the IUD birth control called Skyla, I'm 18 and have been using this birth control for almost a month but the past week or so I have been bleeding, cramping, my breasts have swollen, I get cold/hot flashes, and I go to the bathroom 4 times more than I used to. And I've also noticed the color of my skin changing a little.
