"before getting on microgestin fe 1/20, i was on yasmin.  i never had any problems with yasmin, although my period was slightly heavier than desirable.  i have been on microgestin now for four months and literally go through 2 full period cycles in a row each month.  it is awful and inconvenient.  my doctor actually put me on the pill because of the reports of shorter periods.  i know that all bodies react differently, but be cautious of this problem, if you do not want to chance it.  i have also experienced severe mood swings, but i cannot discredit it regarding actual birth control.  just remember to take it at the same time, daily."
