The leucorrhea of pregnancy is milky white. After pregnancy, the increased secretion of estrogen and progesterone in the body will cause local edema and congestion in the cervix and vagina, which is a normal physiological phenomenon and generally does not require treatment. If the leukorrhea is accompanied by abnormal color, such as brown leukorrhea, yellow leukorrhea, etc., consider vaginitis, cervicitis, miscarriage, etc. It is best to go to the hospital for routine leukorrhea examination and blood test for progesterone and HCG; if the progesterone and HCG are low, it is likely to cause miscarriage, and progesterone can be used reasonably under the guidance of the doctor to protect the fetus. If the leucorrhea is caused by inflammation, it can be treated with anti-inflammatory suppositories or antifungal suppositories, such as metronidazole suppositories or ketoconazole suppositories, under the guidance of the doctor. However, improper use of medication can affect fetal development, so medication during pregnancy must be used with caution.
