"trivora was very effective in preventing pregnancy. however almost immediately after i began pack 1 i experienced yeast infections due to the high levels of hormones. the symptoms went away once i took some over the counter creams. i&#039;m currently on the end of pack 3 and i&#039;m getting off of this pill because i&#039;ve experienced bloating, stomach cramps and really really bad gas! i&#039;ve never had a gas problem until i began trivora. so this gas cramping occurs during random times daily.. and it&#039;s a problem! so i can&#039;t wait to try something different."
