The difference between a case holiday and a miscarriage is mainly based on the time of bleeding and the color of blood, as well as the difference in the nature of pain. The amount of bleeding in miscarriage is generally less than that in menstruation, and may only be manifested as bloody leucorrhea. However, the amount of menstrual bleeding is relatively large and the time is relatively long, which is easy to identify. The time of abortion is generally irregular, which may be at any time during the menstrual period. The regular time of menstrual bleeding is not more than seven days earlier or later. The color of abortion bleeding is pink, bright red or dark brown, and the menstrual bleeding is generally dark red.
