The color of the leukorrhea during pregnancy is the same as the usual leukorrhea, which is milky white and has no odor or only a faint fishy smell, which is the normal color of the leukorrhea during pregnancy, but the increase in estrogen during pregnancy will lead to an increase in the amount of leukorrhea. During pregnancy, you must pay attention to strengthen the local care of the vulva, wash the vulva and change the underwear every day, do not have the habit of using pads, because the use of pads may lead to poor local ventilation, which will cause pathogenic bacteria to multiply and cause vaginal inflammation, and even retrograde infection, resulting in the possibility of intrauterine infection, so vulva care during pregnancy is particularly important. If the color of the leucorrhoea becomes yellow or bloody during pregnancy, and if it is manifested as vulvar itching, you should go to the hospital for examination and treatment in time to avoid serious consequences.
