endometriosis
"I have been on this pill for about four years.  My Doctor took me off of Ortho-Tri Cyclen because of ovarian cysts.  My only compliant is the EXTREME swelling in my ankles and when it's really hot.  I was recently put on Yaz and had to be taken off so they put me back on this.  Otherwise, it would be a great pill but the swelling is getting old and I am sick of dealing with it."
