Slight abdominal pain in this condition usually lasts for 1-2 days and is mostly a normal phenomenon. Because the essence of ovulation is that the mature egg is ruptured by the ovarian cortex, there will be a small rupture of the ovary at this time, and then a small amount of blood will flow out of the rupture of the ovary, through the corresponding ultrasound examination, a small amount of pelvic effusion can be found, and at the same time there will be a corresponding slight lower abdominal distension, discomfort, the duration of which is within 1-2 days, and most of the time, the woman will be quite tolerant of this discomfort. However, if active bleeding from the rupture site persists and is heavy during ovulation, and thereafter luteal rupture will gradually become apparent, if the above situation is more serious, the bleeding is heavy and rapid, active treatment is required if necessary.
