The fourth degree of cleanliness of the leukorrhea can only indicate that a woman has vaginal inflammation and a bad vaginal environment. This condition does not necessarily affect pregnancy, so it is normal to get pregnant when the leukorrhea is bad, and pregnancy depends mainly on the endometrium and the condition of the eggs. During pregnancy, pregnant women with abnormal leukorrhea need to be treated, because severe vaginal inflammation can sometimes increase the risk of infection and miscarriage. Also, poor leukorrhea conditions can lead to uncomfortable symptoms in pregnant women, such as itching of the vulva, as well as yellowing of the leukorrhea, vaginal odor, etc. During early pregnancy, it is also possible to have a gynecological examination and, if the condition requires it, to use medication under the guidance of a doctor.
