birth control
"Yes, this medication is effective if you want to practice abstinence.  I have had this implant since August of 2014, I bled for the first 4 months. I took a PO birth estradiol for 2 months to stop the bleeding. It helped for the 2 months and then I began bleeding again. I feel exhaused all the time and feel bloated most of the time.  I was a runner and healthy eater before, have kept it up for the last year (mostly by forcing myself to get up and go when I used to run for enjoyment).  Since I started with the Nexplanon have gained 15  lbs. I do not recommend this implant.  I am scheduled to get it taken out this week."
