How long it takes to get pregnant after miscarriage needs to be analyzed on a case-by-case basis, taking into account the type and timing of the miscarriage, and cannot be generalized. In the case of early spontaneous miscarriages, and if the miscarriage is not performed, the endometrium is less traumatic and the endocrine effects are not significant. Therefore, after three menstrual cycles, such patients can prepare for pregnancy again when there are no abnormal indicators in the review. In the case of abortion or inevitable miscarriage, i.e., those who have undergone the operation to remove the uterus, from the perspective of eugenics, it is better to wait at least six months before conceiving again. This is because it takes at least three months for the body’s ovarian function and endometrium to recover. It is also important for patients to undergo a thorough physical examination before preparing for pregnancy. In addition, regardless of the form of miscarriage, it is damaging to the uterus, so it is recommended that the patient must recover well before getting pregnant, and not to get pregnant too soon, which may affect the recovery of the uterus and lay the foundation for the growth and development of the fetus.
