"i have only had skyla for about 5 days now, but this is my review so far. insertion was painful to me - lots of intense pressure and cramping. the good news is that the whole process only takes about five minutes. i&#039;ve been pretty crampy and have had minimal spotting (both are normal). the only time it&#039;s been nearly unbearable was the first day. i had the worst cramps of my life (no exaggeration and i always have crampy periods) for several hours after insertion and no amount of ibuprofen or heat helped me. it has been tolerable since, just a bit tender and uncomfortable. if you&#039;re going to get the skyla, understand that it&#039;s going to take time for your body to adjust and it&#039;s no walk in the park at first but it does slowly get better."
