"i love mirena! i got it put in 6 weeks after having my daughter and yes it hurt and i cramped after but i just had a baby so it was nothing i couldn&#039;t handle. i had it put in a little less then a year ago and i just stopped getting periods. i have light spotting and i still get my symptoms of a period. i love having mirena because i don&#039;t have to remind myself to take a pill and i also love how effective it is. mirena is more than 99% effective at preventing pregnancy.
