What exactly are those big red clumps in the toilet after having my period?
Those big red clumps are blood clots and commonly occur during one's menstrual cycle when blood/tissue clumps together.
Menstrual clots are lumps of coagulated blood or tissue. They are discharged from the uterus during menstruation when the lining of the uterus or endometrium sheds and is expelled from the uterus through the cervix. Normally, the uterus produces substances known as anticoagulants, or blood thinners, to allow the thickened endometrium fragments and blood mixture to pass more freely through the cervix and be expelled. However, sometimes if the blood doesn’t flow freely out of the cervix or vagina in a certain period of time, blood will also naturally clot from it’s normal clotting factors if it is sitting still for too long. It also still has to come out and will then be expelled as a small blood clot.
