"i&#039;ve been on zovia for 5 years, and haven&#039;t noticed any side effects. no weight gain, in my breasts or elsewhere. before birth control, i had a very light 4-5 day period, on zovia, it&#039;s nearly non-existant, a pantyliner is all i need. i haven&#039;t needed a tampon in 5 years. i take zovia almost religiously on-time everyday, and 5 years and counting, no pregnancies! other birth controls that i tried really messed with my emotions and i spent a lot of time crying for no reason, so i&#039;m very, very happy with zovia for not messing up my hormones to the extent that i experience mood swings."
