What is threatened miscarriage? What harm does threatened miscarriage do to the body? Is there

Patient's question:

No

Doctor's answer:

Preterm labor refers to vaginal bleeding, followed by intermittent lower abdominal pain or back pain before 28 weeks of pregnancy. Pelvic examination shows an unopen cervix, intact membranes, no discharge of fetal tissue, and the uterus is of appropriate size for the gestational age. If symptoms worsen, it may progress to inevitable miscarriage.
