To determine if you are pregnant, you should first look at your history of intercourse and see if you have menopause, which means that when you come to menstruation, your period does not come, and at this time you will also have some early pregnancy reactions, such as dizziness, nausea, even vomiting, drowsiness, and breast pain. Ultrasound will also be done to see if there is a gestational sac in the uterine cavity. The most common reasons are probably vaginal inflammation and so on. Therefore, when the leucorrhea increases and is accompanied by other symptoms, such as odor, vaginal itching or vulvar itching, you should go to the hospital for a checkup to see if there is any inflammation.
