Implanon
"I have been on Implanon for most of my 20s. I'm currently on my 3rd dose. You would think your body would get used to the hormone by the 3rd dose but my periods have been different every time! 1st time: light bleeding, then none for rest of time, 2nd time: light irregular bleeding, then more frequent and prolonged at 2 and a half years, 3rd time: light - normal irregular bleeding. Just had period 4 a week, stopped a few days, light bleeding for a few more days, then stopped again. A side effect which I experience quite often, is sore breasts. Sometimes I have mood swings but I'm unsure if it's a side effect of the Implanon or due to the fact that I've had depression in the past."
