"i got my skyla in august of this year. i previously had the nexplenon and loved it. i&#039;m 24, never had children and had not had period from 6/2014 to 8/2016. i was not informed to take any kind of muscle relaxer or anti-inflammatory beforehand. the insertion was terrifying and painful. the &quot;test&quot; probe hurt so bad that i pushed out the speculum. which meant that they had to start all over. the cramping was painful and i was so glad i did it on a friday. since insertion, i have had a period every month and the cramps are excruciating. i also get sharp pains when i am not on period. i called the doctor today and told them what was going on. they told me that i need to go back to the nexplenon asap."
