There is one pool of blood, so that any sample will have both young and old red blood cells.
It's blood that has been there for awhile (old blood).
The blood from your period should be dark, not bright, red because it is "old" blood that the uterus sheds. It is also normal to see clots or lumps of blood during your period.
Brown and thick period blood usually appears at the very beginning or very end of your period, or in small amounts between periods. This is just old blood, so old that it has changed color.
Because it is old not fresh
It's the old blood.
Because it is old, not fresh
it means that the blood is either old
Black or brown blood is just old blood. Nothing to worry about.
About every month a woman gets rid of an egg from her womb (period) and the 'blood' that is expelled during a period is the old "blood rich" lining of ones womb. At the beginning of a period, the blood looks redder because it is freshly being sloughed off (sliding off, sliding away) from the walls of the uterus. As the period progresses, the blood becomes darker, indicating it is old blood. (Meaning: If a doctor saw bright red blood, it indicates a new "bleed"-- anywhere in the body. Old blood is dark red to light or dark brown, meaning old blood and therefore of less concern unless it is in vomit.)

In the first few days of your period it's the old blood coming out and that is always brownish. It gets lighter after that.
Spotting after your period can mean the following things: * Left over blood from your period. * Old blood. * Urinary tract infection. * Pregnancy related. * Vaginal infection. * Irregular period. answer sounds to me that was left over period blood no need to worry. -
