"i kept nexplanon for all 4 years and got a new one about a month ago. 8th grade, when i first got it. i was 5&#039;0 117 pounds, 11th grade i am now 5&#039;1 155 pounds. looking back at the side effects, i get all of them, not even thinking its the birth control. now i wonder how i would act and how i would look without nexplanon. my mom recently just made me an appt to get it took out next month. if anyone would like a update after taking it out i will let you know."
