"i had this out in 11 months ago. i had consistent spotting for 4 months. it wasn&#039;t a period but definately needed a tampon of sort. the insertion was a little discomforting but not painful but i&#039;ve had 4 kids so my cervix isn&#039;t super hard as opposed to someone who hasn&#039;t had a child. the cramp i had after the insertion was really bad though. it felt like someone kicked me in the back. it only last a couple hours and went away with some motrin. i&#039;ve had a couple periods that last like 10 days and has averaged about every other month. overall it&#039;s ok... i&#039;m 11 months not pregnant so it must be working."
