Skyla Spotting and Acne

Hello! I got my Skyla inserted about a month and a half ago. The insertion was fine (very little pinch) and I spotted only for two days and I was fine. I thought I was one of those lucky ones, but I was wrong. I got my first period since the insertion on Aug. 13th and I am STILL bleeding (it's as if my period never ended). Some days they look like brown spottings, some days they look like red and fresh blood. It feels like I have been on my period for a whole month. I get occasional cramps, and I noticed I am also breaking out a lot more now. Is this normal? Did anyone have the same experience? When would my spotting go away? (I am so tired of wearing a tampon everyday) Would the acne get better once my body adjusts??
