"i was on kariva for about 6 months and gained about 15 pounds. it regulated my period just fine but i had to go up like 2 pants sizes and had to buy all new bras. i used to be a size 0-3 (depending on brand, usually around a 2 though) but went up to a 5-7 on kariva. once i switched to apri, my breasts stayed about the same size but i lost all of that bloated water-weight that i had on kariva. on kariva, i was sooooo bloated every single day and it was miserable. i was all squishy and plump and considering i gained all of my weight on my stomach, wearing anything other than sweatpants felt horrible. do not recommend."
