If the egg and sperm do not combine on the eighth day of ovulation, there is usually no discomfort. If the egg and sperm combine to form a fertilized egg on the eighth day, most of the egg will be transplanted to the uterine cavity to settle, grow and develop, and the woman may experience lower abdominal pain and swelling, or a small amount of vaginal bleeding, or an increase in vaginal discharge. During this time, a blood test for chorionic gonadotropin (CGT) levels can be performed. If the CGT level is elevated and exceeds 10 IU/L, it is suspected that the chances of early pregnancy have increased. However, in rare cases where the fertilized egg develops slowly or reaches the uterine cavity in a shorter period of time, the chorionic gonadotropin level is less likely to be elevated, and therefore it is possible to have the hormone level rechecked again in a week’s time for a more accurate result.
