abnormal uterine bleeding
"The first month was ok,  but this is my second month of use, and I started bleeding (moderately) in the second week of the pill pack! No fair! I should be into the "no bleeding zone" right now! I am less than thrilled. I feel gross, bloated, and have cramping and  low back pain. I am only on the pill to keep regular, to avoid anemia, but this month it's doing just the opposite! I don't know if I should stay on it and give it more time, or go to something else. Ugh!"
