The increase in leucorrhea during the luteal phase is mainly related to the changes in hormone levels in the body, which is generally normal because the luteal phase will soon enter the secretory phase, followed by the onset of menstruation, so the increase in leucorrhea at this time is generally normal. If the amount of leucorrhea simply increases and there is no yellowing or odor, no special treatment is needed. If the nature of the leucorrhea is abnormal, such as foamy, purulent or yellow-green leucorrhea, you should be alert to the possibility of gynecological inflammation. You need to improve the routine examination of the leucorrhea in time to clarify whether it is bacterial vaginitis, trichomoniasis or mycotic vaginitis, and take corresponding treatment measures for different inflammatory diseases.
