Which birth control?

Melissa • Just call me Mel

I've been wanting to get on birth control for a while now but have recently started really looking into it. I initially wanted to get the implant but have been researching and found that some people gained weight and I'm so scared of that happening because I have only recently started to become confident about my body. I also already have acne that has just started to get better and definitely do not want it to get worse! Also, I have just recent come off of Prozac (depression medication) and have been feeling great without it and I really don't want to have to start to use it again. I'm open to any other birth control methods, I'm just having a hard time desiring which is best for me. Any advice?
