Which is the best form of contraception?

Hi, I'll try to keep this short. So I'm currently on the pill (microgygon) and am thinking about coming off it due to some symptoms I've been having such as mood swings and the rest of it. I've researched into lately it and am totally put off by it, I also lead a busy life and don't usually take it at the same time every day. I've been on it for about a year and due to my heavy periods and bad cramps, my doctor instructed me to take 3 packs at once and then have a break, I honestly feel uncomfortable doing this now as from what I've gathered it isn't good. Please give me any info relevant and help me out! Thanks so much :) 
P.s my doctors honestly aren't much help to me, they all have different opinions on the matter.
