Physiological cysts appear and disappear as you progress from one menstrual cycle to the next, usually do not show any symptoms or need any intervention. Ovarian cyst may sometimes burst causing severe pain and bleeding but cyst as a whole may not come out.
Ovarian cysts may be classified according to whether they are a variant of the normal menstrual cycle, referred to as a functional or follicular cyst. Ovarian cysts are considered large when they are over 5 cm and giant when they are over 15 cm.
Cysts in the ovary often don't cause any symptoms. If they're large, you may feel either a dull or sharp pain on one side of your pelvis or abdomen. You may also feel bloated, or a heaviness in your lower abdomen. If the cyst ruptures, you'll feel a sudden, sharp pain.
