You may not. Ovulation is most often silent whether fertile or infertile. Many infertile women ovulate as infertility cause is not ovulation problem. Some women can feel a slight discomfort at ovulation. We have tests to determine ovulation: see http://bit. Ly/mvk3em. I have a video of details: http://bit. Ly/nsjhg3. See references for more details. Best wishes.
