I Am 19. 180. I Was A Little Less Than

I am 19. 180. I was a little less than 160 before I started with Nexplanon. I am getting it removed on 3/31, at which point I will be choosing another form of contraception. It has made me very tired, hungry, and moody all the time. Obviously, the weight gain is my main reason for wanting it removed. I want to know if there's really a birth control out there that will just allow me to lose the weight I have put on, since no matter what I do on Nexplanon, I can't lose it.
