birth control
"I have had the Nexplanon in for about 2 1/2 years and I could go months without my period which I loved but when I get it it will last for weeks and I will have bad cramps and PMS. Also even when I'm not on my period I will be moody and emotional. My sex drive is completely gone, which is a huge problem because I'm 19 and in a relationship so it sucks and almost makes me want to get it out early.. But it's just so convenient to have, you don't have to worry about taking anything or using anything to have sex. I would recommend it because it affects everyone differently but I may not get a new one in just because of some of the side affects for me."
