The pain that you experienced or inoculation is caused by the trauma that occurs on the outside of the ovarian wall. I would suggest that you schedule an appointment with your OB/GYN. Ovum that develops into follicles within the ovary become "ripe" or ready to ovulate sometime near the mid part of your cycle. There is no duct or hole in the ovarian that is there to let the ovum out. Thus, it must break through the wall of the ovary. For most woman this event causes too little trauma to be felt. For other woman, they experience a small amount of cramping pain that occurs when the ovum bursts out. Sometimes there is a small amount of bleeding
that can occur because of ovulation. Because cramping is a common feeling in the pelvic area and could be due to other causes, I would be hesitant to attribute your pain to ovulation, especially if it lasts 2 to 3 days which sounds to me to be a bit long. Therefore, I would suggest that you schedule an appointment with your OB/GYN to discuss this issue further. Perhaps after further description of the pain and a pelvic exam, the two of you can come up with a few different possible causes of this pain which should give you some reassurance.
