The yellowing of the leucorrhea during ovulation is a symptom of the luteinizing phase after ovulation, when progesterone starts to increase, causing the leucorrhea to be sticky, milky or yellow. If there is no itching, odor or redness, it is a normal phenomenon. Paying attention to personal hygiene is fine and will not affect pregnancy preparation and fertilization of the egg. However, when ovulation occurs during ovulation and the leukorrhea is yellowish, you may consider the presence of vaginal inflammation or abnormal hormone levels. You may also consider performing routine leukorrhea tests to rule out any increase in white blood cells, positive hydrogen peroxide, and whether trichomonas or bacterial infections are present. Based on the test results, we can prescribe medication to cleanse the vulva and vaginal plugs to treat the yellowing of the leucorrhea.
