Under normal circumstances, in the case of a natural miscarriage, the gestational sac is usually expelled within one week, and the decidua tissue is also expelled within one week. If there is still bleeding more than one week after a natural miscarriage, it is imperative to visit a hospital for related examinations, typically requiring an ultrasound to observe the miscarriage situation. If the miscarriage is complete, then there are generally no major issues. However, if the miscarriage is incomplete, a dilation and curettage procedure may be necessary. It is possible for an incomplete miscarriage to occur naturally. Therefore, if there is still bleeding after one week, further examinations are necessary. In cases of natural miscarriage, it is usually advised to wait at least six months before trying to conceive again, and relevant examinations must be conducted before attempting again to determine the causes of the natural miscarriage and to treat accordingly.

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.

Natural miscarriage impact on the body

If a woman experiences a natural miscarriage, it can have adverse effects on her body. If attention is not paid to local cleanliness and hygiene during uterine bleeding, and the body's resistance is lowered, it can easily lead to some gynecological infections. If the inflammation is not treated in time, it can affect future normal pregnancies. Furthermore, if care is not enhanced after surgery, and rest is not adequately observed, it will impact the uterus's normal contraction and recovery, leading to continuous vaginal bleeding, which can also affect future pregnancies. Additionally, it can also have some adverse psychological effects on the pregnant woman.

Can a natural miscarriage be completely cleared?

After a natural miscarriage, whether it can be completely cleared varies from individual to individual. Some women may have a complete miscarriage naturally. However, some people may have existing gynecological inflammation or be relatively weak, which can lead to incomplete miscarriage, necessitating further uterine cleaning. After the miscarriage, women should closely monitor their vaginal bleeding and abdominal pain. Normally, after such a miscarriage, abdominal pain should last about two to three days, and vaginal bleeding should clear up within a week. If vaginal bleeding persists for a longer time and abdominal pain occurs, the possibility of residual materials in the uterine cavity should be considered, and it is advised to go to the hospital for further ultrasound examination and subsequent treatment as needed.

How long does it take for the lochia to clear after a natural miscarriage?

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.

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.
