"i had my nexplanon placed in my left arm on november 1, 2012. i was not sexually active until i was married, but i have been a testing bunny for several birth controls since the age of 14 due to extremely painful and long-lasting menstrual cycles for which i have been hospitalized several times. my body rejected all of them. when i was married and became sexually active, my husband and i both worried about getting pregnant too soon and this option was not estrogen-based and long-lasting. i bled sporadically for 3 months and then have had random spotting for short periods every 3 months or so. i have had few side effects, i don&#039;t have dangerous periods anymore, and i have a lot fewer migraines. i will replace mine at the end of year 3."
