"probably worst experience of my life. i did like the convenience of the implant being in my arm and not having to remember to take a pill or have something up my vagina. however, nexplanon was not for me. i went through terrible mood swings (from being happy one moment to coming close to crying for no reason a few minutes later). my period was pretty much non-existent, which was something i was looking for in a birth control. but, i gained so much weight (accumulating nearly 30 lbs). no matter what i did to lose weight- which i did through working out at least an hour six days a week and cutting my caloric intake to less 1,200 a day- it still did not work. i am getting it removed tomorrow so i&#039;m hoping i will be back to myself soon!"
