"i am 20 year old and i started taking microgestin in august of this year. i started gaining weight, breast getting bigger, retaining a lot of fluid , and mild hair loss. i didn&#039;t notice any of this till now i&#039;m in my second month and my mom told me she can tell j have a lot of fluid in my body . my feet swelled up and all. my breast are really tender most of the time which i hate. my sex drive has increased which is a plus, and my periods last about 4 days. as far as the acne , it is crazy i went to the dermatologist and she told me this birth control is prone to acne , but maybe it might go away after a few months. i will come back and update you guys ! as everyone said side effects are different for everyone ."
