"mirena was the most convenient birth control method that i had used (out of the pill and the iud) and i did not mind it at all. overall, mirena was great but i had only had it for 9 months. i wasn&#039;t getting my period and i wasn&#039;t too happy with that (as odd as that sounds). i just wanted to be regulated and have a lighter period, but i didn&#039;t want it to be completely eliminated. because of that, it had me paranoid and i would have to take a pregnancy test every month. other than that, it was fine. my boyfriend and i both couldn&#039;t feel the strings and there was nothing wrong. i&#039;m 18 and i just figured that i should try another form of birth control that allows me to still have regular bleeding."
