Etonogestrel
"I had nexplanon for a year and 6 months. I bled the entire time- at least 15 days a month. It wasn't a full flow, but it was always there and there was no rhyme or reason to the bleeding so I couldn't even plan for it. It worked as in I'm not pregnant, but I couldn't take the bleeding. I kept hoping it would adjust to my body, but never did. My doctor said many women have the same result and that's why they get it removed. It's been gone a month and I have not bled since aside from my actual scheduled monthly period. It's great to be able to know when I'll be bleeding. My acne is completely gone as well (it wasn't severe, but my face is spotless now and nothing changed aside from removal). Insertion and removal was easy and painless."
