Sometimes your property can be taken against your wishes, or for some other reason it can be lost. The Real Estate License Exam will ask you about these types of situations, generally known as involuntary alienation. Questions on involuntary alienation will most likely be definitional, so remember the chief characteristics of each of the forms.
1 Ovarian wall rupture: The ovaries have no openings; at ovulation the egg breaks through the ovary's wall. This may make ovulation itself painful for some women.  Fallopian tube contraction: After ovulation, the fallopian tubes contract (similar to peristalsis of the esophagus), which may cause pain in some women.
In brief: A few days. Pain related directly to ovulation, sometimes called mittelschmerz, ' is usually only a few days. Obviously there is personal variability, but one or two days is very common. There can be pain indirectly related to ovulation or not related at all that might make pain go on longer. I suggest if pain lasts longer than about 4 days checking with a doctor may be helpful.
