menstrual disorders
"This is my fifth month on Lo Loestrin 24 Fe. First month was normal, second month I stained heavily for 4 days, third month I didn't get it, and the fourth month I stained heavily for 9-10 days, then got my period a week and a half later for four days. Next month I stained lightly on and off and I started my sixth month about two weeks ago and still no period."
