"i had kyleena inserted in may and my periods have been getting better lasting just 1 week every month.  the only con there is to it is just getting it put in you will cuss like a sailor because of the pain, but luckily it doesn&#039;t last more than a minute and i never had a baby before.  my partner doesn&#039;t feel it during sex, i had no mood changes, no acne, no weight gain, it&#039;s the best birth control ever!! i will get it again in 5 years"
