"Never pregnant,28,retroverted small (6cm) uterus.  My regular Period = severe cramping,vomiting,heavy bleeding,miss work. Skyla recommended to decrease cramping w/ low hormone side effect risk. Negative past experience with other hormonal BCs (nuvaring:extreme fatigue,combo pills:visual migraines,POPs:super depressed &amp; anxious). Insertion was extremely painful but quick.  Barely noticeable cramps for 2 days, pain-free after (but vag dryness).  After 1 wk, started having excruciating pain caused by laying/sitting(back,stomach,pelvic,upper thigh cramps that woke me from sleep every 3-4 hours,lasting several hours);600mg ibuprofen no help, slow walking did. 4 Days of this,removed (mild pain &amp; quick).  Relief was immediate.  PPGyno said this was a first in her experience"
