What are the indicators of a miscarriage? 

Just before miscarriage, pregnancy symptoms such as tense breasts and morning sickness may decrease. Usually a miscarriage begins with blood loss. The bleeding can increase within hours or days and can be severe. The embryo will exit your body as clots and pieces of tissue (uterine mucosa). This can be accompanied by menstrual or contractions-like pain. The blood loss then decreases rapidly and stops after a few days. Sometimes a little (brown) blood loss will remain for a few weeks. It’s also possible that it’s discovered that the embryo is no longer alive during an ultrasound, even though no blood loss has been experienced. You can expect bleeding within a few days (sometimes weeks), as the embryo is being rejected.
