"i&#039;ve been taking sprintec for 3 months now. i have experienced some side affects. my hormones were unstable so my body had to adjust. when i start a new pack i notice i become sensitive and cry over anything. my periods are lighter. i have not gained weight. my breast have not gotten fuller. i notice i do get nauseous sometimes but rarely. but the beginning was horrible. this is the first birth control i&#039;ve ever taken so my body was not used to the hormones and had to re-adjust (i&#039;m guessing), i would have major mood swings, cry for everything and get really nauseous. not sure how my boyfriend handled me when i first started taking the pills. but they are super effective and i rarely get mood swings."
