"i&#039;ve had the implanon for about 5-6 months now. i&#039;ve gained about 8 pounds within those months. it is a very effective birth control, but i&#039;ve never been so moody and angry in my life. ever since i&#039;ve got it my boyfriend and i have noticed my moods being completely different and awful. not only have i gained weight, but its also making me break out really bad.  my acne will not go away no matter what i try to use."
