"i&#039;ve been on yaz a year now and love it. i&#039;ll be honest, my first 2 months were difficult. spotting, painful breasts, depression, exhaustion. but now i&#039;m so glad i allowed time for my body to adjust. no mood swings or depression, my sex drive has increased, my skin looks great and my periods are highly predictable. i will always get it on a tuesday night and lasts only 2-3 days with light spotting and very little cramping. i&#039;ve also dropped a good 15lbs! my doctor said it&#039;s rare, but possible, to bleed every month and still be pregnant while on the pill. so i do take a pregnancy test every few months to be on the safe side since i rely on the pill as my only form of contraception and my periods are so light. for me that&#039;s the only drawback."
