After pregnancy, various discomforts and abnormalities can occur, and increased leucorrhea is one of the minor problems that can be difficult to talk about. If the leukorrhea is merely increased, colorless and clear, without odor, itching or other uncomfortable symptoms, there is no need to worry, let alone treat it, as it is often a normal part of pregnancy. The most common abnormality is a positive test for Candida (commonly known as mold), which may be accompanied by thick, pea-like leucorrhea with vulvovaginal itching, or no symptoms at all. Candida is a normal parasite of the vagina. After pregnancy, the vagina becomes more moist and under the effect of high levels of estrogen and progesterone, the shedding cells of the vagina increase and the intracellular sugar increases, increasing the chances of rapid growth and reproduction of Candida. Therefore, the chance of vaginal Candida infection during pregnancy increases significantly. For vaginal Candida infections found during pregnancy, those with symptoms can be treated with topical medication. Since the general saline method of leucorrhoea examination does not have a high detection rate for Candida (less than 50%), topical antifungal treatment can be attempted with typical symptoms, as long as beanbag-like leucorrhoea is seen, even if the leucorrhoea examination does not reveal Candida, and is often effective. Clotrimazole for vaginal use is a safe and effective drug to use during pregnancy, with no adverse effects on the fetus. If Candida is detected in the vagina in late pregnancy, a vaginal treatment with long-acting clotrimazole can be used at 36-38 weeks of pregnancy to “cleanse the birth canal” and avoid the possible effects of Candida on the baby during vaginal delivery. Trichomonas vaginalis infection may also be found during pregnancy and can be treated with oral methotrexate or vaginal tablets of methotrexate, which will not adversely affect the fetus. The FDA classifies methotrexate as a Class B drug and the American College of Obstetricians and Gynecologists guidelines recommend that methotrexate can be used safely during pregnancy. In addition, increased vaginal fluid in mid to late pregnancy sometimes needs to be differentiated from premature rupture of membranes, so if you can’t tell for yourself, go to the hospital and let your doctor help you.
