Thanks for the query.
During pregnancy the vaginal discharge
will increase and that is called as physiological leuchorrhea.
If you are not having symptoms like smell, excessive itching etc. no need to worry.
If any of these symptoms appear better to consult gynecologist once and get examined.
Because any type of infection during pregnancy
should be treated carefully.
Keep local area clean and dry as per as the possible, use only luke warm water to clean the area.
