What is the fleshy tissue that comes out during menstruation?

Hello, Menstrual blood discharged during a woman’s period results from the shedding of the uterine lining (endometrium). This blood contains a significant amount of metabolic waste and toxins accumulated within the uterus; incomplete expulsion may harm the uterus. The passage of a clump-like substance along with menstrual flow is highly likely to be shed endometrial tissue, as menstruation itself involves endometrial shedding accompanied by bleeding. However, the presence of such clumps cannot entirely rule out pregnancy; therefore, a pregnancy test using a home pregnancy test strip is recommended for confirmation. We hope this information is helpful to you. Wishing you a happy and healthy life!
