What do you suggest if I'm just wondering if anyone has had a skyla IUD or a mirena (levonorgestrel) and if so what side effects?

Talk to doctor. Women experience the Mirena (levonorgestrel) in different ways. Most women dont have any ill effects, and just enjoy the decreased bleeding. Many women will stop having periods, some have lighter periods, and some have irregular bleeding. The Mirena (levonorgestrel) is not associated with weight gain, breast tenderness, headaches, etc. You should discuss this with your doctor.
