Miscarriage happened naturally, not induced. The baby, placenta, and membranes have all been expelled and there is nothing left in the uterus. Very early miscarriages, before 7 weeks gestation, are usually complete. A scrape of the uterus may be necessary. This can be detected by ultrasound.
Kids having kids' is an apt description.
And it's distressing that one in five pregnant teen will have to experience a miscarriage. But not all miscarriages have to happen. Educate yourself if you're pregnant. Knowledge is power. Several drugs can cause abnormalities in the unborn child.
