Patients with embryonic arrest and miscarriage clearance need to rest for at least 6 months before pregnancy to provide sufficient time for physical recovery and psychological preparation. Pregnant women who experience embryonic arrest and need to be given clearance surgery in the clinic are advised to consider pregnancy preferably after six months after the surgery, because the endometrium needs some time to repair, and if pregnancy occurs too early it may lead to preterm abortion or spontaneous miscarriage due to poor endometrial environment. After the embryo stops developing and miscarriage, the endometrium of the patient has a recovery process and if the body is in a bad state at this time, it should take the opportunity to adjust the body. And before getting pregnant again, women need to undergo preconception eugenics examination in advance to exclude undesirable factors. When embryonic arrest occurs for 2 or more times in a row, it is recommended to find out the cause and treat it before pregnancy. It is recommended that when preparing for pregnancy, both spouses should pay attention to strengthening nutrition, ensuring that they stop smoking and drinking, and exercising appropriately to enhance physical fitness as well as improving the quality of sperm and eggs.
