Is it serious if menstruation hasn't returned three months after a miscarriage?
If menstruation has not returned three months after a miscarriage, it is usually not serious if due to another pregnancy; however, if caused by severe uterine damage, the situation is more serious.
A miscarriage refers to the termination of pregnancy before 28 weeks of gestation or when the fetal weight is less than 1000g. A pregnancy loss before week 12 is considered an early miscarriage, while loss from week 12 up to but not reaching week 28 is termed a late miscarriage. Miscarriages are classified as either spontaneous (natural) or induced (artificial). Early miscarriages further include missed miscarriage and habitual miscarriage. Generally, if a patient does not resume menstruation within three months after a miscarriage because they became pregnant again during recovery due to lack of contraception, the condition is usually not serious and there is no need for excessive concern—simply maintaining healthy lifestyle habits is sufficient. However, if menstruation has not resumed three months post-miscarriage due to significant uterine damage and poor recovery, the condition is typically more serious and requires timely medical evaluation and treatment at a hospital.
Patients should ensure adequate bed rest, avoid overexertion and strenuous physical activity, maintain a healthy diet avoiding binge eating, and engage in moderate exercise while avoiding intense physical activity.
