"this is my first experience with birth control. i began taking lo loestrin fe in january, and am just beginning my eighth week. my periods were normal before this experience, but i haven&#039;t had one since i started this bc - for me personally, not a pleasant side effect (my periods were not too painful or heavy, and it was a comfort to know i was not pregnant). my breasts have been extremely painful, and it has only gotten worse with time. i find it very difficult to get out of bed, and i am far more easily angered than before i started this bc. it has also caused moderate/severe constipation. i am going to ask my doctor about a different pill when i am finished with this pack. overall, would not recommend based on my experience."
