birth control
"I have been using Nexplanon for four years deciding to get it before enlisting in the USAF, and it hasn't caused any problems or adverse side effects. They numb the area where they insert the implant initially, and when it's time to replace it. You feel pressure, but in my experience no pain. While using this implant I have had very infrequent periods. Or some heavy ones that lasted for only two, versus a week without the implant. I haven't gained any weight, though workout regularly so haven't noticed any effects. Acne hasn't been an issue. I have been happy so far with this implant, and haven't needed to look into any other forms of birth control, and would recommend this to a friend or anyone thinking about getting it."
