"i&#039;ve had my mirena iud in for about two months and i couldn&#039;t be happier. getting it in was more painful than i expected and i had fairly intense cramping for about twelve hours afterward. by the next day i was at 100% and have had very few side effects. the spotting can be annoying, but my regular period has stopped entirely and my doctor says the spotting will stop soon. i wish i had done it earlier!"
