An occasional stabbing pain in the ovary is not a symptom of pregnancy. If you experience an occasional stabbing pain in the ovary during ovulation, it may be caused by a ruptured follicle, also known as ovulation pain. It is often accompanied by ovulatory bleeding and other conditions. If ovarian stabbing pain always occurs during non-ovulatory periods, it may be caused by ovarian lesions, such as ovarian cysts, ovarian cancer, or ovarian inflammation. When a woman has appendicitis, the appendicitis can also cause right ovarian pain radiologically. If a woman is pregnant, she will experience mild implantation pain when the fertilized egg is laid, mostly as a cramping sensation or mild pain in the middle of the lower abdomen, rather than pain on one side. When women experience occasional bursts of ovarian pain during non-ovulatory periods, it is recommended that they go to the hospital as soon as possible for relevant examinations, such as pelvic ultrasound and gynecological internal examination, in order to confirm the diagnosis and treatment in a timely manner.
