"i take ocella to help control my pcos and as a birth control. it&#039;s done a good job of regulating my period and as a birth control. however, i&#039;ve experienced many mood swings and depressive-like symptoms as well as more nausea and tenderness in my breasts. it does what it needs to do which is why i&#039;m reluctant to switch since it is one of the best birth controls to regulate my pcos symptoms."
