"i had the nexplanon put in on march 2014. when i first got it in it felt like my nerves were being pinched whenever i would bend my arm. on top of that, i had horrible mood swings and heavy periods that would last up to 3 weeks. now that i&#039;m onto my second year i have a lot of random spotting, i&#039;ve lost my sex drive, and i gained a lot of weight. had to go on this bc because i&#039;m really bad with pills and it seemed really nice because i wouldn&#039;t have to worry about it after getting it out in. still not too sure how i feel about it. i know some girls who&#039;ve been on it for years with no problems. but the fact that my periods came back makes me worry that it&#039;s becoming less effective."
