birth control
"I would recommend this to anyone. I first had implanol at 19, back in 2009. I had a two week long period and that was the last period I've had. I'm now 24 and coming to the end of my second implant and I can honestly say I have had no bad side effects. When I was on the pill I came out in terrible acne, I had none with this implant. I haven't had any weight gain but I've always been around 150-160 pounds. 
I'm living in the UK so for me (thanks to our amazing heathcare) this product is free, but I would pay for it if I had to. You have it changed once every three years and you're sorted until next time or you decide to have a little one. Fab."
