Vaginal spotting can occur anytime during your reproductive and postreproductive years. It can be the sign of a medical problem, but in some cases the cause may be benign or unknown.
Vaginal spotting is a light amount of bleeding that occurs for various reasons in a woman's cycle. This spotting is sometimes referred to as "old blood" or "in-between bleeding."
Colour and Consistency
Vaginal spotting is normally pink, red or brown in colour. The consistency can be sticky or pasty (usually the case when mixed with vaginal discharge) or watery like blood.
Blood in the form of spotting can be as light as a pin prick or heavy enough to wear panty liners. Bleeding any heavier than this is considered irregular bleeding.
Spotting lasts anywhere from a day to a few days. In some cases, spotting may last longer than this or become a regular occurrence.
Some causes of vaginal spotting are pregnancy, vaginal dryness, hormonal imbalances, use of birth control pills, vaginal injuries and miscarriage.
