menstrual disorders
"I was on Ocella for about 10 years for PCOS.  Worked great.  Then I got off for about 2 years and was regular.  Had a miscarriage early 2016 and went back on it.  It has been horrible this time around.  Horrible cramps , heavy breakthrough bleeding that starts the second week and lasts until about 3 days b4 period starts.  I have been taking since Jan and it is now Dec and never improved.  Gyno switched me to sprintec.  Fingers crossed."
