"i have had the implanon since may of 2009. i liked it at first, no problems. but, it is now 2 and a half years later, my periods usually last 3-4 weeks, heavy, then i am off for about 2 weeks. it is awful! along with heavy, long periods, i have gained 30lbs. even before having my son, i was on a very healthy diet and exercised 5 days a week, if not more. sadly enough, i can&#039;t get the weight to budge! i think the implanon just is not right for me, so i am going to take my chances with the pill!"
