Increased discharge during late pregnancy is mainly caused by fluctuations in estrogen and progesterone and is usually normal. However, abnormal increase in vaginal discharge may also occur, and there may be differences in the color, shape and smell of the discharge in both cases. Common causes and treatment 1. Increase in normal discharge: The increase in estrogen and progesterone in pregnant women’s bodies and the approaching birth in late pregnancy can lead to an increase in vaginal discharge, which is usually white or creamy, flocculent, highly viscous, without fishy odor and without uncomfortable symptoms, and generally does not require special treatment. 2. Itching and other symptoms. It can be caused by inflammatory diseases such as bacterial vaginitis, mycobacterial vaginitis or trichomoniasis, and in serious cases, premature rupture of fetal membranes and fetal distress. It is also important to pay attention to cleanliness in daily life to ensure the health and hygiene of the vagina, and usually try to wear loose underwear and change clothes regularly.
