Skyla IUD.

So I had the Skyla iud placed probably about 5 months ago now..the main reason I got it was to help with the cramps and bleeding I had been going through. Before I got the IUD placed I had been bleeding for over a year straight. At first my IUD helped greatly and I was doing good. But now my cramps are getting bad again and I've been bleeding for over 2 weeks. Anyone else have this problem?
