Midcycle Pain or DiscomfortSome women experience a twinge, a cramp, or some discomfort in the lower back or abdomen when ovulation occurs. Women sometimes notice a small amount of vaginal discharge, sometimes containing a small amount of blood, during ovulation. For some women these symptoms are severe enough to be mistaken for an ectopic pregnancy or appendicitis. Other women experience headaches, gastric pain, or a general malaise; while others women experience feeling much better during ovulation. When women experience these symptoms during ovulation it is called Mittelschmerz or midcyle pain.

Ovarian cysts are fluid-filled sacs, similar to blisters. Ovarian cysts are common among women during their reproductive years and are growths that form on either of the two almond-sized glands on each side of the uterus. Most types of ovarian cysts are harmless and go away without any treatment.

Polycystic Ovary Syndrome
Polycystic ovarian syndrome (PCOS) is a hormonal disorder that affects an estimated seven percent of all women. It is the most common hormonal disorder among women. According to experts, the actual number of women affected by PCOS may be as high as one out of ten simply because so many cases remain undiagnosed. Why are so many cases of PCOS undiagnosed? Since the symptoms can vary from woman to woman it is often difficult to accurately diagnose polycystic ovarian syndrome. Because polycystic ovary syndrome can cause significant long-term health consequences, a quick and accurate diagnosis, followed by proper treatment is urgent.

Ovarian cancer is often called the "silent" killer because many times there are no symptoms until the disease has progressed to an advanced stage. One-third of American women will get some form of cancer in their lifetime and approximately 1.4 percent of those cases will be cancer involving one or both ovaries.
