"i am 22 years old and although i use condoms, i&#039;ve decided to stop using them and i wanted to be extra careful not to get pregnant. before getting the implanon i was on depo-provera the 3 month shots. the shots worked better for me. since getting the implanon i have gained at least 7 pounds. i have decided to keep the implanon. i am also nauseous, kind of often, but other than that i am okay. and it gives me a chance to focus on my future and one less thing to worry about in my relationship. word of advice: be prepared to workout to keep your shape."
