The uterus will not be enlarged during the ovulation period. Ovulation is a normal physiological period for women, during which the vaginal secretion will increase, similar to egg white, which is transparent and has a particularly good pulling degree, which is unique to the white belt during ovulation. In addition, during the ovulation period, there will be changes in body temperature, for example, on the day of ovulation, the basal body temperature will drop to a minimum, after ovulation due to the formation of the corpus luteum, the basal body temperature will rise, which is a relatively clinical symptom in the ovulation period. If the uterus is enlarged, most of the time it refers to localized cervical enlargement, often due to chronic inflammation of the cervix, resulting in tissue hyperplasia, which increases the size of the cervix, and may cause pain in the lumbosacral region, which has nothing to do with the ovulation period.
