"i&#039;ve been on this birth control since i was 16 years old (i&#039;m now 27). i have never had any problems with it. when i first started taking it my boobs grew by 2 cup sizes in a short period of time but that could have been coincidence. i very rarely have acne and i haven&#039;t experience any mood swings or loss in libido. i do ocassionally have breakthrough bleeding, but that&#039;s to be expected with any kind of hormonal birth control."
