ovarian cysts
"I really like this birth control pill.  Has made a huge difference in my skin over the past few months.  I have been on several different types of birth control pills in the past 11 years and these are definitely the best I have taken.  I did experience some spotting/break through bleeding during the first pack, but the benefits overshadowed that by far.  I have had shorter periods, less pain, great skin, good moods, and increased sex drive."
