Etonogestrel
"This month was my two year mark of having the implant in. I have not had a full period, or used a tampon once in the last two years. I have about one, rarely two, days of very light spotting approximately once every three to four months. My fiancé always finishes inside of me, without a condom or another form of birth control, and we have never had any issues or concerns. Nexplanon definitely serves it's purpose in my case. However, I have slowly gained about 30 pounds in the last two years, while eating well and exercising. I cannot get the weight off, and may get the implant out to lose weight before my wedding. Overall I'd recommend Nexplanon as it's serves it's purpose. If it weren't for the weight gain I'd get it done again."
