Inflammation of the cervix during pregnancy can affect the fetus to varying degrees. Mild cervicitis, usually does not have much effect on the development of the fetus, as long as attention is paid to daily cleaning. However, pregnancy secretes a large amount of estrogen and progesterone, which may further aggravate cervicitis. If the condition is serious, it may manifest as increased vaginal purulent discharge, bladder irritation signs, lumbosacral pain, etc. It may expose the fetus to infection by related pathogens, affecting fetal development and increasing the risk of premature rupture of membranes, preterm labor, and miscarriage. It is recommended that women during pregnancy should undergo regular obstetric checkups, pay attention to daily cleaning of the vulva, change underwear frequently, and consult a professional doctor in time if there is any discomfort, so that professional measures can be taken for treatment.
