It is inaccurate to say that there are signs of ovulation in women, but not necessarily 10 of them. Generally common are: mildly elevated body temperature, increased vaginal discharge, lower abdominal pain, bleeding during ovulation and so on. 1. Mildly elevated body temperature: During ovulation, the secretion of progesterone increases, leading to a mild elevation of body temperature at the end of ovulation. Generally the body temperature rises 0.3 to 0.5 degrees Celsius compared to the pre-ovulatory period. 2. Increased vaginal secretions: During ovulation the glandular cells of the endocervical lining will secrete cervical mucus under hormonal stimulation. Therefore, women may experience an increase in leukorrhea, which is usually in the form of a clear, pulpy discharge. 3. Lower abdominal pain: ovulation causes or follicular fluid or small bleeding to stimulate the peritoneum, so women may experience hidden pain on one side of the abdomen. 4. Ovulation bleeding: During ovulation, estrogen levels suddenly drop, resulting in the endometrium will fall off, causing a small amount of vaginal bleeding, usually bleeding lasts 3 to 5 days. Because of the different hormone levels in each woman’s body during ovulation, there are differences in the symptoms that occur.
