birth control
"I'm 17 years old. I had the Nexplanon inserted 1 year ago.  I was getting the Depo shots for 2 years before I got the implant because I had very heavy and long periods. I got sick of going in every month for a shot so I figured getting the implant that lasts 3 years would be perfect and I wouldn't have to worry about getting pregnant. I haven't had a period since I got the implant, no spotting or any bleeding at all. I didn't gain any weight from it. Its not common for people to gain weight from it. But if you do eat healthy and exercise and you should be fine."
