Etonogestrel
"I tried this after experimenting off and on with pills, Depo-Provera, and barriers over the past 5 years.

Pros: Transitioning immediately from Depo-Provera to Nexplanon, I have had 0 bleeding. Convenient. Insertion was quick, easy, and I experience little pain. No need to revisit the clinic every month or three months.

Con: I have noticed some weight gain. After receiving the implant on Dec 6, it is now Jan 7 and I have gained about 3-4 lbs. This makes me a little nervous, as I feel this could easily spiral out of control quickly. I'm afraid to think of what the scale will say in another month."
