Etonogestrel
"I have had Nexplanon since January 9th and so its been a little over 2 months since I've gotten it inserted. I was nervous about getting it inserted but the whole process is a breeze, so if you are considering it don't worry about that! For 2 months, I bled almost every day but it wasn't bad. As time went on, it was less and less. I've read other reviews where they said they bleed everyday and was horrified about that happening to me, but it was hardly noticeable. Sex wise- I haven't gotten pregnant and this is the only form of protection my boyfriend and I use. Also, I didn't get any acne but for the first month, I would get nauseous easily after doing cardio or even after having 1 alcoholic beverage. But that has gotten a lot better."
