"i&#039;ve had the implanon put in 2011 and taken out 2013. then the explanon put in 2014 and taken out today 10/19/2016. as far as preventing pregnancy and no period (for me), it&#039;s exceptional. but i&#039;ve gained 40 pounds over the course of 2 years and it&#039;s nearly impossible to lose weight while on this birth control. also, i did get break outs on my face from bad acne from time to time. now, i&#039;m currently getting ready to try the &quot;mini pill&quot;."
