Birth control

So i thought I would ask you lovely ladies a question about birth control. My fiance are getting married in june and we want to get her on birth control before the wedding. We heard that bc that isnt matched to her hormons and stuff make women really really moody. Also, we dont have a whole lot of money and dont want to go to planned parenthood. So does anyone have any advice? Does it really make women moody is you arent match up with it? Are there any cheaper ways to get matched up with bc?
