If you have undergone a curettage operation after a fetal arrest, the time for you to get pregnant again should be at least three months later. Because the embryo stops developing, there are many reasons, it may be the embryo itself, the development is not normal, or the pregnant woman has inflammation or endometrial abnormality, which may cause the embryo to stop developing. The first time the embryo stops developing, in the next pregnancy, if there is no obvious disease, such as the pregnant woman has no systemic chronic diseases, and uterine fibroids, endometrial polyps or ovarian tumors, caused by the embryo stops developing, need to be treated in a timely manner, if there is no such reasons, you can continue to prepare for pregnancy. If there are no such reasons, you can continue to prepare for pregnancy. If the embryo stops developing for more than two times, you must do a comprehensive checkup before getting pregnant again.
