Ovulatory Pain is felt when Ovarian Follicle will begin to swell and eventually rupture in the process of Ovulation, ejecting Ovum into the abdominal cavity where it is picked up by Cilia and swept into the Fallopian Tubes. Some women may feel this swelling and rupture as a sharp pain or more precisely, a twinge in their lower abdomen and usually on the right side. This phenomenon is also known as ‘Mittelschmerz’. Some woman may also experience a small amount of bleeding at this juncture. About a quarter of all woman are estimated to experience this convenient and accurate indicator of Ovulation, however, some may experience a much less precise nature with no sudden onset in the form of a ‘twinge’. While some may experience a dull ache, which may persist for a day or longer, this may or may not indicate an Ovulation and as such, observation on other ovulatory symptoms are highly recommended.
