During ovulation, the leukorrhea increases, is clear as well as stringy, and usually has no odor. A woman’s leukorrhea is affected by the body’s estrogen, which increases during ovulation and helps sperm enter the uterine cavity and combine with the egg to fertilize the egg. The leukorrhea during ovulation is usually colorless and transparent, and is accompanied by low back pain, fatigue, and abdominal distension. If a woman’s ovulation leukorrhea appears yellow, green, or even with blood, these are abnormal leukorrhea, and it is necessary to go to the regular hospital to receive routine leukorrhea examination to clarify its specific causes. Whether a woman’s leukorrhea is normal or not can often be a direct reflection of her health, so women are advised to closely observe the changes in their leukorrhea.
