What should I do if there is mild itching in the vagina during pregnancy?

Patient's question:

Patient Age: 26
Detailed Condition and Purpose of Consultation:
During pregnancy, around the fourth month, there might have been a slight infection, with mild itching in the vagina. What should be done?

Doctor's answer:

1. Leukorrhea Test: Through the leukorrhea test, it can be detected whether there are gynecological diseases or various bacterial infections causing vaginitis. Generally, the leukorrhea test includes: vaginal cleanliness check; presence of molds and trichomonas; clue cells; amine test; pH value, totaling five categories.
2. Colposcopy: Through the colposcopy examination, it can be detected whether there is early cervical cancer. It can accurately distinguish between tumors and inflammation. However, due to the limitations of colposcopy, it cannot directly see the condition inside the cervical canal, making it difficult to detect lesions within the cervix.
