What is the reason for yellowing in the crotch area of pregnant women's underwear, and how to wash yellow underwear?

Patient's question:

No

Doctor's answer:

Hello, first point, your personal hygiene is not very good, you don't often clean the private parts, and you don't often change and wash underwear. Second, you may have mild gynecological inflammation. It is recommended that you go to the hospital in time, and after the doctor examines and diagnoses, treat it in time and correctly according to the examination and diagnosis results. Wish you a quick recovery.
