In the early stages of pregnancy, the leucorrhea should be the same as usual, milky white, or colorless, clear, odorless, or slightly fishy mucus. During pregnancy, the leucorrhea may be slightly more than before, because it is affected by the hormonal secretion in the body. After pregnancy, there will be an increase in estrogen and progesterone, and after the fertilized egg is laid, there will be an increase in chorionic gonadotropin, which will easily lead to an increase in secretion. During this period, you should try to pay attention to hygiene and washing to avoid excessive accumulation of leucorrhea at the vaginal opening, which can easily cause bacterial infection. If there is an increase in leucorrhea with blood, the first thing to consider is an aura of miscarriage and you should first check the progesterone level.
