"the first month was the worst. i had a lot if mood swings and very tender breasts. after that the side effects have been very minimal. i no longer have my period, but around the time i used to get my period every month i get light cramps. i also get very tender breasts during this time but they have gotten bigger since taking the birth control. the only major complaint i have is that i&#039;ve had a major decrease in sex drive as well as being very tired in the morning. i switched to this birth control because i got very sick every morning. i like this one much better."
