It is possible for the leucorrhea to increase before pregnancy. Pre-pregnancy leukorrhea can occur because of an increase in cervical mucus and cervical discharge at the time of ovulation. The increase in leucorrhea before pregnancy is due to the different increases in hormones in the body that stimulate leucorrhea secretion. The increased secretion has a protective effect and protects the organism from upstream infection by bacteria. However, it should be noted that patients cannot judge whether they are pregnant based on increased leucorrhea. If you have sex without contraception and have delayed menstruation, along with symptoms such as breast pain and darkening of the areola, it is recommended to visit the obstetrics and gynecology department of the hospital and cooperate with the doctor for an early pregnancy test. If the result is positive, it means that you are pregnant. Before pregnancy, women need to pay attention to a balanced diet, regular work and rest, ensure a relaxed mood, reduce stress, and pay attention to personal hygiene and warmth to prevent gynecological inflammation.
