birth control
"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 "normalize""
