A procedure called hysterOScopy, when a small camera is passed through your cervix into your uterus, can be used to check for this problem. Sometimes scar tissue can be repaired at the same time.

But even if that's not the case for you, you should know that any procedure that dilates the cervix (a necessary step during many abortions) can weaken it. So if you've had more than one abortion and get pregnant again later on, you may find that you have what's known as cervical weakness; a weakened cervix that may start dilating prematurely. This can sometimes be treated with a stitch, called a cerclage, to keep the cervix closed.

On the bright side, having conceived before proves that you ovulate and that your fallopian tubes are open; both important factors in making a baby.
