If you have a history of abortion, whether it can be detected during the marriage test depends mainly on how many months of pregnancy you have had an abortion in the past. If you have had an abortion in the early stages of pregnancy, or a medication abortion, you will not be detected through the marriage test. If you have had an induced abortion, clinically, because the embryo is relatively large, the opening of the uterus needs to be opened wide before the embryo can be discharged, and after the embryo is discharged, the cervix changes from the original round shape to a transverse cleft, so you can find out whether you have had an abortion in the past through the marriage test. In addition, for large months of induced abortion, when the abdomen will be enlarged, some people will also appear stretch marks, of course, this is not an absolute clinical manifestation to determine whether the abortion has been performed.
