Birth control

What’s the ideal birth control? Because a few of my friends have had different types of then between them. Some are on the pill but that’s messed up their period and one still managed to get pregnant on it. Others have had the implant and caused them pain and i’ve seen a video of the removal of it and it didn’t look up my street. And ones got the injection.

My mum was talking to me about getting the pill or something (because the world isn’t safe and just being careful) and I’ve been thinking about it but I’m not sure on which ones best for me. How do I decide what to do and which one to go for?
