Etonogestrel
"I got Nexplanon BC in January 2015, so almost a year now, and I have had only one week out of this whole year that I have not bled, constantly. I have gained at least 30 lbs. I have never had bad acne, but it seems that the implant has helped with that, and I'm not pregnant, but who could be after bleeding for nearly 11 months straight. So unless you enjoy bleeding constantly and very severe mood swings and weight gain, I wouldn't recommend it."
