"i got nexplanon on january 6, 2015. i was using pills for 3 years prior. at first it was great, the 99.95% effective got me to want it. i have a mild increase in acne, not super moody, don&#039;t see much change. sex drive is still great with my boyfriend. however, my periods now last over 2 weeks at a time (i&#039;m on mine right now and it&#039;s now the 20th day) they aren&#039;t super heavy but it&#039;s enough that i have to wear a tampon. which is very annoying since i do still have a sex drive haha. anyways, i like it so far besides my periods. if they don&#039;t shorten or disappear i may want to take it out."
