"i used to be on yaz and really loved it but, i was worried about all it&#039;s latest bad reviews.  i just switched to zovia and my breasts are so tender.  i thought it would be great to go up a size (i heard this from a friend) but it is really painful.  i&#039;m also very bloated which i&#039;m not used to because you never get bloated or acne from yaz. i get my period next week so still unsure if it will be as light as it was on yaz."
