"i have been on this pill for a few years off and on. it&#039;s very effective at clearing my skin and keeping me not pregnant, but i have gained fifteen pounds, my periods are a little longer but on time.  i had depression with another birth control pill and switched back to this, and after a year or so i noticed the weight gain back. it&#039;s okay though but my self esteem isn&#039;t as great due to weight gain."
