Nexplanon, bleeding

Madison

About 12 days ago I got the Nexplanon implant, and I've been bleeding pretty much nonstop since. Not a serious flow, mostly spotting, but is this normal? I know it's not my period because I'm not supposed to be for another 2 weeks. I know it has been known to disrupt your usual cycle, but I've been spotting for about 12 days now, and just wanted to know if anybody had experienced this?
