Etonogestrel
"I got it inserted in September 16,2013. Reason I remember the date exactly because I was planning on getting it again, but NO WAY!! Don't get me wrong  it is very effective, but the side effects are horrible! I'm always tired, barely energized, very moody, like I don't remember every crying so much in my life than the 3 years of having this insertion, and don't let me talk about the bleeding! First year I'll say I barely bled, like every three to four months, and it'll last like a week or two. Now I haven't stopped, constantly spotting. I'm going to wait until my 3 years are up to have it removed but I will definitely not get it again. Wouldn't recommend it to no one"
