When I started my research, I was surprised to find out exactly what was in my menstrual blood. I just thought my body decided it needed to bleed for three to five days a month to let me know I wasn’t pregnant and then move on. I had know idea what a period actually was and why women had one every.single.month!
Let me start out by saying that menstrual blood is still just blood. It is not any “dirtier” than blood that comes from any other part of your body, unless you have any blood borne diseases.
Basically we can think of menstrual blood as a “watered down” version of our venous blood. This is because menstrual blood is lacking the proteins regular blood has that makes it thicker, it also has less iron than the blood in our veins.
So, what is in our menstrual blood? There is a mix of blood, bacteria, uterine tissue (which can sometimes cause clumps), and mucus.
Bacteria will naturally accumulate around the vaginal area during your period because the vagina becomes more moist. It is important to note that during the period we are more susceptible to bacterial infections such as bacterial vaginosis, especially if there is an imbalance of bacteria.
