"i have had implanon exactly 2 yrs. i loved this birth control for the 1st yr and a half. i had absolutely no period or weight gain. it was an easy and effective birth control. however last august i started having my cycle again. the bleeding was the heaviest it&#039;s ever been, very clotty, and unexpected. often i would have bleeding every other week.  the length of the period is long, and extremely heavy with cramping! my mood has drastically changed since restarted my cycle. i have depressed feelings and often don&#039;t feel like getting out of bed. after starting my cycle back, i experienced weight gain. went to the gyno yesterday and since starting back in august i&#039;ve gained 30 lbs. no change in my diet and i&#039;m only 21. i&#039;m getting this birth control out!"
