"i&#039;ve been on this birth control for about 2 weeks now, and let me explain i&#039;ve never been on birth control before. i experienced just about no side effects so far, no unusual weight gain, headaches, or cravings. no bad mood swings and it already helping my acne (the reason i went on it). the downfall: i&#039;ve been bleeding for the whole 2 weeks i&#039;ve been on it. i started it the day of my period as instructed, usually i bleed for 4-5 days but i have had my period now for 2 weeks straight. i think it&#039;s getting light and about to go away and then i wake up the next morning and back again! if this side effect continues into the next pack i may have to give up beyaz:( i am on the generic by the way."
