"i have been on this implant since february of 2015. i have constantly been bleeding. it can be medium to hardly anything. i have had roughly 5 days ( spread out) of no bleeding since and its june 2 now. the effectiveness is excellent! i wouldn&#039;t go to anything else for the effectiveness, but the bleeding is a downside but i can handle it. the doctor has given me medicine for 30 days at a time ( i have been on another dose for another 30 days but going back soon)  it seems to work a little but not very much. i have no weight gain and am 115lbs. not much of moodiness than what&#039;s expected for a 16 year old girl."
