Some patients often ask how they can master ovulation and whether they will feel it during ovulation. Ovulation can be judged mainly from the following aspects: 1, the basic body temperature rises: normal women before ovulation, the basic body temperature is low, after ovulation rises, the temperature difference between the two in about 0.5 degrees, the intersection of high and low temperature for the day of ovulation. 2. Leukorrhea changes: the leukorrhea increases during ovulation, is thin, clear and transparent like egg white, and increases in filaments. 3. Ovulation pain: The majority of women do not feel any obvious pain during ovulation, but a few will feel pain in the abdomen. The reasons are mainly due to (1) the increase of gravity in the follicle before ovulation, which can lead to pain; (2) during ovulation, due to the rupture of the follicular membrane and ovarian envelope, the follicular fluid will stimulate the nearby peritoneum, and some more sensitive people (with lower pain threshold) may experience abdominal pain; (3) after ovulation, due to the closing of the uterine tubes during ovulation or bleeding during ovulation to stimulate the pelvic organs, pain can also occur. pain. This pain is usually mild. Since ovulation can occur alternately on both ovaries or persistently on one side, the pain episodes can alternate between left and right or can be seen on one side more often. The abdominal pain usually occurs around the time when the basal body temperature rises.
