The phenomenon of increased leucorrhea at the beginning of pregnancy is normal, but the leucorrhea should not be watery. The leucorrhea at the beginning of pregnancy should be like thin nasal discharge, transparent and without odor. If there is watery leucorrhea, it is a sign of vaginitis, which should be combined with individual clinical symptoms and routine examination of leucorrhea to make an accurate judgment. You should also pay attention to hygiene during pregnancy, pay attention to washing and keep your pubic area dry and clean to avoid the breeding of bacteria. If the condition of vaginitis is not serious, medication is not recommended, just pay attention to hygiene in general. If there are obvious symptoms of vaginitis, you should also apply intravaginal medication in time, otherwise the condition will develop seriously and lead to infection in the uterine cavity, which will also affect the growth of the fetus.
