"i&#039;ve been reading some of these reviews, and felt the need to say that everyone will react differently. i have just completed my first week of this pill and haven&#039;t noticed anything too extreme. i just had some mild vaginal discomfort, but nothing bad at all. i was on my old birth control for just over a year, but switched pills because of breakthrough bleeding and cramps. from what i can tell, my mood or sex drive hasn&#039;t changed at all."
