If the miscarriage is before the 3rd month of pregnancy, whether it is an induced abortion, a medicated abortion or a spontaneous abortion, there is no need to hide it, no one can find out, and even the doctor has no way to know if there is a history of miscarriage before the 3rd month of pregnancy. Because there are neither stretch marks nor changes in the cervix when the abortion was performed before the 3rd month of pregnancy, and the ectocervix is still rounded, there is no way for the doctor to know whether there is a history of abortion or not. However, if the miscarriage is induced in a large month, such as 4 months or more, the cervix will be transversely cleft, so there is no way to hide it from the doctor. At this time, there may be no stretch marks, but if the labor is induced in a larger month, such as 7 or 8 months, there may be stretch marks and the cervix is also transversely cleft, so there is no way to hide it.
