There is no special time for marriage checkups, they are usually done before pregnancy. If the marriage is registered now, depending on which day the couple has time, they can go to the local maternal and child health institution for the checkup. If you are already married, it is not too late to do it now, mainly to better prepare for pregnancy. The marriage test focuses on checking for infectious diseases, such as syphilis, AIDS, condyloma acuminata, etc. Due to the different living customs in different places, there will be some differences, subject to the requirements of the maternal and child health institution where you live. If you are afraid that both parties have infectious diseases, you should be tested before you get married, because there is an obligation of confidentiality after the HIV test, so that you do not not tell the other party to cause physical harm. If you are planning to get pregnant, you can do the preparation work after the wedding test.
