Has anyone heard that it is now a guideline of ACOG that any miscarriage after ten weeks be tested. Well, I mean that the parents be genetically screened for clotting disorders. My OB never mentioned this. I have a friend who lost a her second pregnancy because, that later guessed, of a clotting disorder. Her third baby was born in bad shape, but fine. Her fourth pregnancy she was taking blood thinners the whole time, and the baby was healthy and full term.
