The pill to the shot

So I've been on the pill for four months now and it's regulated my period, made it shorter, and I barely have any cramps. Problem is it's a pain now to take it everyday. I don't want to have to worry about taking birth control everyday. I'm getting bad at taking it and I don't want to get pregnant. So, I'm  thinking about switching to the depo Vera shot, thoughts ? Thanks !:)
