"i have been on yasmin for a long time but began having break through periods after my third child. my doctor switched me to zovia and within 3 weeks i gained inches on my hips and thighs. i work out twice a week and watch what i eat so this was concerning. i also developed a lot of acne on my face. big red sores that were painful. i have since switched back to yasmin and my side effects have reversed. thankfully. it may have been due to the increase in the amount of estrogen from the zovia."
