birth control
"I had Implanon inserted May of 2012. Once it was inserted, I continued to have a period for 6 months non-stop, which caused some other issues. Once that stopped, I had periods for two weeks, and then would be off for two weeks, and then back on. This went on for a year. Now they come and go as they please. One thing that I've had a hard time dealing with though is the weight gain. I gained 10 lbs in just one year, and during this second year I have gained 5 more lbs. I have never in my life had an issue with weight (gaining or losing), but this has been it for me. It has also given me extremely painful periods. It HAS done it's job in preventing pregnancy though! Which I am pleased with!"
