"nexplanon was prescribed to me as a continuous hormone therapy. w/o birth control my emotions would become so unbearable, sporatic, and logically unpredictable i could not function nor communicate the cause. 
because i do not have to remember to take an extra pill a day i am able to function.  
nexplanon has been the best birth control opt for my needs so far. after 3 months today i first experienced a period. which may be due to intentionally increased weight (1-2lb) and increased exercise. usually, unless i track my caloric intake i weigh ~90#. 
i was told that 6 months was the time expected for the drug to &quot;normalize&quot;"
