Etonogestrel
"I've had this in for 2 years now and I love it. I guess everyone responds differently but I haven't experienced any acne breakouts, moodiness, prolonged periods... Etc. In fact, I haven't had a period in 2 years. Lots of sex, no babies. The one thing I will say though is that it made me gain 15 pounds within the first 3 months but other than that no further weight gain"
