Implantation Bleeding

Hello, I've never had the implant, and just had a few questions on it.
1. What causes implantation bleeding?
2. Is it normal? I feel like I see it a lot on here so i'm not sure if it's normal or bad or just something that happens often.
3. Where is it inserted?
4. I believe I know the answer to this, but is it a form of birth control?
