"i have been on yasmin for about 4 years now and i have had no problems/ side effects. i have had no weight gain (except maybe a little in my breasts which isn&#039;t an issue for me), have had lighter periods and very little menstrual cramps (and i used to have a full 7 day heavy, and painful period), and can&#039;t even remember the last time i got a pimple.
