"i started taking jolivette 6 months ago after i had my daughter since i was breastfeeding.  after 1 month and a half i was late taking a pill one day and the next day i started my period that last 5 days. then the next month no period.  than the next month i was spotting.  each month as been different and unpredictable. i haven&#039;t had any side affects, besides the fact its a lot harder for me to lose weigh than with my first born. i don&#039;t know if the birth control is the cause but i&#039;m guessing it is. the only negative thing about the pill is irregular periods and weigh gain."
