Birth Control
"I used ocella years ago and it was great at first. My cramps weren&#039;t as painful or etc but then I started getting severe stomach pain and guess what? I found out I had gallstones due to Ocella and had to have my gallbladder removed when I was 20 and I&#039;m 25 now. So if any ladies experience stomach pain on the right side you might have gallstones due to this pill"
