"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&#039;m not on my period i will be moody and emotional. my sex drive is completely gone, which is a huge problem because i&#039;m 19 and in a relationship so it sucks and almost makes me want to get it out early.. but it&#039;s just so convenient to have, you don&#039;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."
