Generally, lochia can be cleared within a week after a natural miscarriage occurs. The duration of lochia discharge during a natural miscarriage is also related to the length of pregnancy. If the miscarriage occurs during a later stage of pregnancy, there may be a longer period of vaginal bleeding because the endometrium is thicker, potentially requiring about ten days. Typically, it will clear within a week, and it should not last more than ten days at most. It is advised for women to undergo a medical examination at a hospital two weeks after a natural miscarriage, at which time the recovery of the uterus and any remaining tissues can be assessed. After such a miscarriage, it is important to rest, enhance nutrition, and abstain from intercourse for a month.

What are the symptoms of a natural miscarriage?

During a natural miscarriage, the most typical clinical symptoms include abdominal pain and vaginal bleeding. Based on the different symptoms of a natural miscarriage, women should undergo differential diagnosis. When a woman experiences abdominal pain and vaginal bleeding, it may initially suggest a threatened miscarriage. If the abdominal pain worsens and vaginal bleeding increases, it could progress to an inevitable miscarriage. An inevitable miscarriage can further be classified into complete or incomplete miscarriage. In the case of a complete miscarriage, the abdominal pain generally subsides gradually, and the vaginal bleeding eventually stops. In contrast, during an incomplete miscarriage, the vaginal bleeding lasts longer, and the abdominal pain is prolonged. At this point, it is necessary to visit a hospital for an examination to check if there are any remnants in the uterine cavity and to receive further treatment.

How long after a natural miscarriage can one have sexual intercourse?

Following a natural miscarriage, there are wounds inside the uterine cavity that need to heal through a restoration process continuously repairing the endometrium.

One month after a miscarriage, with a doctor's guidance and upon confirming that the body has recovered well through examinations, sexual intercourse can be resumed. Within the first month, it is crucial to prohibit sexual activities, including sitz baths and swimming, to reduce the chances of infections. Post-surgery, there should also be appropriate advisement.

How long is it normal to bleed after a natural miscarriage?

A natural miscarriage generally stops bleeding within a week; if the bleeding continues beyond a week, it is considered abnormal. This is because in most cases of natural miscarriage, the embryo and the decidua are expelled together, followed by uterine contractions, resulting in some vaginal bleeding. Normally, such bleeding should not persist beyond a week. If vaginal bleeding continues past this period, an ultrasound should be conducted to examine whether the uterine cavity is clean and free of any residual embryonic tissue. If remnants are found, it may be necessary to take some medications to promote blood circulation and remove the residual tissues.
