Normal leukorrhea does not affect pregnancy. If leukorrhea increases along with itching and odor in the vulva and vagina, it may be an infection of vaginal inflammation, which may have an effect on pregnancy and requires timely treatment. The type of vaginitis should be clarified by routine leucorrhea examination and treated actively. Simple vaginal inflammation can be cured in about 7 days after a course of treatment and you can prepare for pregnancy. If you have increased leucorrhea frequently, you should consider whether you have cervicitis or gynecological malignancy and undergo cervical cancer screening. If there is no abnormality in the screening test and the increase in leucorrhea is caused by cervicitis or vaginitis, you should actively treat it before preparing for pregnancy.
