IUD Brands which one is the best?

Jess

Okay ladies, I'm planning on getting an IUD soon and I'm debating between Kyleena or Mirena. I've heard some things about both of them.. I get heavy periods, and I have to wear super tampons with a pad. If I don't then its, "Hello bloody underwear!" I weigh about 115lbs (a lil less) and I'm 23.. I've been on the pill for 5 years, because I felt like I was dying on my period before I started birth control. But I think an IUD will be much better for several reasons.. So which IUD do you think is better, Mirena or Kyleena?
