Skyla IUD. The Skyla IUD contains a progestin which thickens your cervical mucus and sends a constant signal to your uterine lining not to grow and to get mature. It is common to have irregular bleeding at first as the receptors in the uterus are being primed and then periods usually become very light and you skip periods. Your negative pregnancy tests are not invalid. Hope this helps.
