What does it mean if you have a brown stringy discharge after your menstrual period?

Depends: Depends on where this is happening in your cycle. This could still be part of your period at the end. It could happen with mid month spotting after ovulation. It may be normal but it is tough to tell without a proper examination. Other factors such as infection, growths, bleeding disorders, pregnancy, medical conditions can cause abnorma discharge, spotting, or bleeding.
