"zero stars. i became pregnant in october 2016 with the skyla in place. i had nexplanon for a year and a half after my first daughter was born but changed to skyla because of irregular cycles and mood changes. i had skyla put in place in july. i felt sick in mid november and thought i had flu. i hadn&#039;t had a cycle but didn&#039;t worry because the strings were in place. after experiencing nausea and cramping, i took two pregnancy tests which came back positive. i went to the doctor and i was six weeks pregnant. i had the iud removed. i am posting this here to let others know of a true failure case and to tell you to have it placed with ultrasound. we are coping with the pregnancy but were shocked to say the least."
