Skyla IUD

Anyone have a good experience with skyla? I went for my mirena today and my ob said my uterus measured on the small side at 6 cm, which increases the risk for it coming out. She recommended a smaller IUD even though I had a mirena before pregnancy for 5 years. I asked if this would be the Kyleena and she said yes, but the nurse ended up coming back with the skyla and that’s what she put in. I didn’t realize the hormone difference between the two smaller IUDs and didn’t have time to do my research. Now I’m worried about abnormal bleeding and periods and my wedding is in 11 months. Mirena completely stopped my periods.
