Etonogestrel
"I had this put in my arm in March of 2014. I have always had a problem with the spotting. It is so much more annoying and very inconvenient at times. I have the worst possible mood swings, I am so angry to my boyfriend and I feel awful because then 2 minutes later I will be loving again. so its very confusing to him, and me as well. I'm sick of the mood swings, and the weight I've gained with it, I used to have such a flat skinny tummy and now I don't anymore. I wouldn't recommend this to anyone, yes it prevents pregnancy but going through an emotional roller coaster and not knowing when your going to be done really sucks and is not worth the pain."
