When these problems occur, for first time pregnant baby mothers feel panic and don’t know what to do or what is causing them. For pregnancy, increased vaginal discharge is a normal phenomenon. Pregnant mothers just need to pay attention to the nature, color and smell of their discharge to understand some of the problems their body is experiencing. After pregnancy, vaginal discharge increases as long as it is because of a series of changes in hormone levels with pregnancy. Estrogen keeps increasing, which directly acts on the glands of the cervix and vagina, prompting an increase in secretions, which will protect from external viruses; furthermore, with the increasing size of the fetus, it compresses the pelvic cavity and vagina, causing it to be congested with blood and increasing mucosal exudation, so this increase in pregnancy secretions It is a normal physiological phenomenon and does not need treatment. If a pregnant mother notices yellowish discharge, odor, itching and burning sensation in the vulva and vagina, she should be alert to the occurrence of vaginitis.
