birth control
"Initial insertion was painful but after a few days it got better with the cramping. However after that I had cramping everyday and had to take ibuprofen and the last couple of weeks I had very painful cramps. Went today for my follow up appointment (a month after insertion) to check placement. The sonographer found that I had a ruptured cyst on one of my ovaries she explained that could have been the reason for the recent painful cramps. Looking up adverse reactions on the Bayer's website says that cysts are an adverse reaction. So beware that can happen when you get Kyleena. My doctor said that the IUD doesn't cause cysts but right on their website it's listed as an adverse reaction. I don't know what to make of the IUD  if seems like a lot risks."
