Heavy discharge in early pregnancy is mainly due to the increase in estrogen levels in the body after pregnancy, which causes an increase in female discharge. In the early stage of pregnancy, the level of estrogen is very high, and under the effect of very high estrogen level, it will stimulate the cervical glands to secrete a lot of mucus, and women will feel the increase of vaginal secretion. However, the discharge does not have an odor and does not cause vulvar itching or pain in the vulva and vagina. It can also be caused by vaginal inflammation. If a woman does not pay attention to vulvar hygiene in the early stages of pregnancy, vaginal inflammation is more likely to occur, as women’s resistance is poorer during this period. For example, common vaginal inflammatory diseases include bacterial vaginitis, trichomonas vaginitis and mycotic vaginitis. For this condition, topical vaginal medication such as nifurtimox vaginal soft capsule is needed.
