There will be leukorrhea in the first month of pregnancy, and the leukorrhea will be much more than non-pregnancy, because the estrogen in the body will increase after pregnancy, which will lead to an increase in cervical secretion, and then lead to an increase in the secretion of the epithelial mucous membrane of the vagina, so the leukorrhea will be increased, so there is no need to be nervous. However, it is important to understand the nature of the leukorrhea as well as the color of the leukorrhea, and to know if the leukorrhea has an odor. Normal pregnancy leukorrhea is milky white, no odor or a slight fishy smell, which is normal. If there is yellowish leukorrhea with a strong fishy odor, accompanied by vulvar itching, it is an abnormal phenomenon, which is often caused by chronic inflammation of the vaginal mucosa. It is recommended to go to the hospital to give a secretion examination, and then, based on the results of the laboratory tests, make a clinical decision as to which medication should be used to treat the disease. When you are pregnant, you must pay attention to keep the vulva clean because of the high secretion.
