How long does it take to get your period after a failed transplant?

If the embryo transfer fails, menstruation will generally come one week later. This is because progesterone will be injected for 14 days during the embryo transfer. If pregnancy does not occur, the medication will be stopped, and then menstruation will come one week later. During this period, you must pay attention to good rest, avoid fatigue, maintain an optimistic and cheerful attitude, control your emotions, and do not have sex during menstruation.

The process of fertilized egg implantation is silent and there are no major changes in the body. If the fertilized egg fails to implant, it means there is no pregnancy. If you are not pregnant, your menstrual cycle will continue normally and you will have your period normally. Therefore, if menstruation continues to be normal, it means that the previous fertilization process failed.

1. The fertilized egg itself has defects: The fertilized egg itself has defects.

2. Uterine factors: The failure of fertilized egg implantation is likely due to uterine hypoplasia, submucosal fibroids, endometrial polyps, intrauterine adhesions, endometrial tuberculosis, etc.

3. Immune factors: Research on immune factors in recent years has shown that there are two immune conditions that affect conception. Alloimmunization: Sperm, seminal plasma or fertilized egg are antigenic substances. After being absorbed by the vaginal and uterine epithelium, they produce antibody substances through immune reaction, which prevents the sperm and egg from combining or the fertilized egg from implanting. Autoimmunity: There are autoantibodies in the zona pellucida of infertile women's serum, which react with the zona pellucida to prevent sperm from penetrating the egg, thus preventing fertilization.

4. Ovarian luteal insufficiency: If a woman's progesterone secretion is insufficient, her endometrium will be abnormal, which will affect the implantation of the fertilized egg.

5. Excessive mental stress: especially severe anxiety and excessive psychological pressure due to failure to conceive.
