A member asked:

Menstrual flow is always lighter after blood donation. everyone says it's not connected, but it's been consistently happening to me for years.

Anemia: Well it could be connected or related. If you are suffering from anemia or low hemoglobin levels and you donate blood, that is a mechanism for your body to prevent more blood loss (though your period) and thus more hemoglobin. Check your hemoglobin and hematocrit and you might find out if that is the case.
