Increased leucorrhea is not necessarily due to pregnancy, but may also be caused by a woman suffering from gynecological inflammation. When a woman suffers from vaginal inflammation, cervical inflammation or endometritis, the increase in local inflammatory exudate may lead to increased leucorrhea, vulvar itching and odor. In this case, you need to go to the hospital in time to have a routine test of the white belt and do a gynecological examination to be able to confirm the diagnosis, and you need to give lotions and medication for treatment. If a woman has increased leucorrhea after a delayed menstrual period, and if she goes to the hospital to have blood tests for elevated chorionic gonadotropin levels and a gynecological ultrasound for the development of a gestational sac and the appearance of a fetal bud in the uterine cavity, it is more certain that a woman is pregnant. Therefore, relying solely on the increase in leucorrhea to prove that a woman is pregnant is inaccurate and may lead to misdiagnosis.
