Once the vaginal blood comes in contact with the air, it is not uncomman for the blood to turn black. It is a process knowen as oxidation. ANSWER I have no idea about why it is black but when blood comes in contact with oxygen it becomes brighter red
In a sense, you are both kind of right. In red blood, iron is highly oxygenated. It is in its Iron(III) oxidation state, which is red. When Iron is reduced (oxygen taken away), it becomes Iron(II), which is black. This is usually due to breakdown of red blood cells. In this case, the blood within the uterus (womb) has been sitting there for a few hours before being expelled, and has broken down, causing the RBC iron to be reduced. This may be due to uterine contractions not being strong enough, or temporary blockage of the cervix.

∙ 14y agoOn days when the flow is lighter, it takes longer for the menstrual fluid to leave your uterus and exit through your vagina. During this process it becomes oxidized (thus darkening) and can sometimes even clot (if you've ever had "blobs" that what it is). It isn't really much different than when you cut yourself; scabs are often darker than fresh blood, right? However, if your blood is constantly black, or it is really really freaking you out, talk to your gyno or family doctor. If you have a nurses' hotline they can give you health information as well. Good luck.

∙ 11y agoThe level of oxygen that your red blood cells are saturated with causes a conformational change in the hemoglobin. This conformational change also causes a change in its ability to reflect light. As a result blood that is highly oxygenated is a crimson red whereas blood that is relatively deoxygenated is more of a dark almost purplish color. As we typically draw from veins, the blood that is drawn is of a darker color.

∙ 13y agoIt is due to old (oxidized) blood which has pooled in the uterus before being expelled (or if a tampon has been left in too long!).
