Miscarriage naturally refers to the process where the embryo is spontaneously lost from the mother's body, this is called a natural miscarriage. After a natural miscarriage, the medical suggestion is to wait for six months before getting pregnant again; however, the current view is that waiting at least three months is also acceptable. In our clinical cases, there are instances where pregnancy occurs one month after a natural miscarriage. If there are no symptoms of physical discomfort after the miscarriage, and the follow-up ultrasound examination is normal, in fact, there is no specific mandated period to wait before becoming pregnant again after a natural miscarriage. Nevertheless, waiting at least three months primarily allows the endometrium sufficient time to fully recover.

Does natural miscarriage have anything to do with sperm?

The occurrence of natural miscarriage is somewhat related to the quality of the male's sperm. When the vitality of the sperm and the rate of sperm abnormalities are both decreased, it tends to lead to miscarriage. The combination of sperm and egg requires both to be healthy to conceive a healthy baby. If the quality of the sperm is poor, it might lead to miscarriage even if a fertilized egg is formed. Therefore, before pregnancy, both men and women should go to the hospital for pre-pregnancy check-ups to see if their bodies are suitable for pregnancy. If the sperm quality is poor, it should be regulated, and pregnancy should only be attempted after the sperm quality has been improved.

Do the symptoms of spontaneous miscarriage include bleeding?

During a natural miscarriage, vaginal bleeding occurs. This is because, after a miscarriage, the gestational sac and shed uterine lining also need to be expelled from the body, resulting in vaginal bleeding. Typically, this bleeding lasts about a week, gradually diminishing until it stops. If vaginal bleeding after a natural miscarriage persists for an extended period, even exceeding ten days without stopping, and is accompanied by abdominal pain, it is necessary to visit the hospital for an ultrasound to check for any remnants within the uterine cavity and possibly undergo a dilation and curettage procedure.

What should I do if a natural miscarriage is not complete?

If after a natural miscarriage, there is prolonged vaginal bleeding and accompanying abdominal pain, it is necessary to consider the possibility that the miscarriage was incomplete. In this case, the first step is to go to the hospital for an ultrasound to check if there is any residual tissue in the uterine cavity and the size of any remaining embryonic tissue. Treatment should be determined based on the size of the residual tissue. If the residual tissue is relatively small, about 1 centimeter, it is generally possible to promote uterine contraction and aid the expulsion of the residual tissue by taking medications that improve blood circulation and remove blood stasis. If the residual tissue is larger, exceeding 2 centimeters, taking medication generally does not yield good results, and it becomes necessary to proceed with further surgical cleaning of the uterus.

Does a natural miscarriage require a uterine cleaning (D&C)?

When a miscarriage occurs, whether a uterine cleaning is needed depends on whether there are any remnants in the uterine cavity as shown by a follow-up ultrasound examination, that is, to see if the miscarriage was complete. If the examination reveals significant remnants in the uterine cavity after the miscarriage, then a uterine cleaning treatment is required. Most women do not need a uterine cleaning after a natural miscarriage, as typically the bleeding will stop around 7-10 days post-miscarriage. Therefore, women should focus on resting, improving their nutrition, and enhancing their body's resistance to prevent any potential complications after a natural miscarriage.
