Does the waiting period (iddah) for a pregnant woman end with the miscarriage of her fetus, even if she was only two weeks pregnant?

A miscarriage at two weeks of gestation does not terminate the waiting period (iddah) of a pregnant woman because no human form is discernible in it, nor is it considered a pregnancy that clears the womb. The shortest period by which the waiting period can be terminated by pregnancy is after eighty days, i.e., after the 'alaqah stage. Based on this, a divorced woman observes her waiting period by menstruation (three menstrual cycles), and a widow observes hers by four months and ten days.
