what is the best contraception for me?

🐨👑
So it's only recently that me and my other half had started having sex. I don't want to use condoms and want to try a different method. My doctor once offered me two options, first was the implant and the other was the pill (the type of pill that gets taken every day without stopping) 
I'm not sure what is best for me! I personally wanted the injection but she doesn't think it's a good form of protection.
She came to the conclusion that these were the best options for me because of my weight. I'm 5ft 3 and 15 stone. (Please do not judge me I'm trying to lose the weight) 
I was wondering if anyone has any suggestions? Has anyone tried these methods of contraception before? If so does it work well?
