Doctor's answer:

Mold is a conditionally pathogenic microorganism. Diabetics, individuals undergoing extensive estrogen therapy, long-term antibiotic use, and obesity with skin-pant and synthetic underwear can all lead to mold adaptation and transmission. Menstrual flow varies among individuals, with some having heavier flow and others having lighter flow, but the shortest duration of menstruation should not be less than three days. A lighter menstrual flow indicates thin endometrium, which can interfere with the implantation of a fertilized egg and disrupt childbirth.
