"i took gildess 1/20 for a full year. everything started out fine, but around the 7-8 month mark, my periods started coming in all over the place and my skin broke out like i was in middle school. i either had two periods a month, or none at all. i didn&#039;t notice any weight gain, but did experience occasional mood swings. overall, it prevented pregnancy, but did not give me a regular cycle."
