birth control
"I just recently had my third Implanon inserted. I'm lucky, I have had really no side effects from it. With my last two I had bleeding intermittently, not knowing when it would happen was probably the worst thing. I cannot attribute it to weight gain (although this did happen, but was soon resolved when I started at the gym!). I don't have mood swings or feel highly emotional, I don't get bad 'periods' they are usually light. There are so many bad experiences had by many women and there usually aren't many good reviews put up. My sister got one, she was not so lucky with constant bleeding, so she got it out - I think she gave it 3 months. My opinion is give it a go if doctor thinks it's a good idea get it, you can always take it out again."
