What tests should be done before getting pregnant again after a miscarriage?

Patient's question:

I have had two miscarriages. What tests do I need to undergo before getting pregnant again? Also, my menstrual flow is much less than before, which may be related to the last D&C procedure.

Doctor's answer:

Hello: Embryonic arrest is a common condition in female infertility. Currently, you are not only improving the quality of eggs but also addressing the reasons that lead to embryonic arrest. There are several causes, including some where the embryo itself fails to develop properly and naturally dies, some where insufficient hormone secretion makes it difficult to support embryonic development, leading to death, some where uterine abnormalities prevent the embryo from growing, and some where infections or immune issues are involved. These conditions include diabetes, hyperthyroidism, and others. Once embryonic arrest occurs, it is important to identify the underlying cause. Before the cause is determined, it is not advisable to get pregnant again to avoid further harm. Common causes of abnormal embryonic development include genetic factors, infections, immune issues, exposure to radioactive substances or toxic chemical agents, medications that are contraindicated for pregnant women, high temperatures, and excessive stimulation. If the embryo has defects or stops developing due to adverse factors during the developmental process, the uterus generally recovers within 3 months after a painless abortion. It is recommended that you wait at least 6 months after the abortion before trying to conceive again. Before pregnancy, it is essential to identify the main cause and undergo timely treatment and prevention. Wishing you good health!
