"ladies, 
i must say i am so relieved to read some of these reviews. i have never had a problem with weight in my life and within 3 weeks of the insert of the implanon, i gained 20 pounds. for the past 5 months, i have attempted to lose the weight, but its fairly close to impossible. i&#039;ve been on the implanon for 6 months and i have a removal appointment tomorrow. while i did not experience spotting or lower back pains, i did suffer with headaches very often.
