"i had this put in a little over a year ago. wanted something long lasting as i knew i didn&#039;t want kids for a while (i was 17) and i can&#039;t take pills during basic training. no period for a year. a month ago my breasts started swelling up terribly, i gained about 7 lbs, and i become very moody. (thought i was pregnant) this could be because i just graduated and am training for 5 months very soon, but i think the bar is mainly to blame. my period started yesterday-heavily. i haven&#039;t had it for 14 months. i think it&#039;s still worth it though (my insurance covers it). no real responsibility and time without the period was nice.
