If a person miscarries before five weeks, sometimes called a "chemical pregnancy," they may have what feels like a normal, even painless period. But most miscarriages involve some cramping. A person may also pass blood, fluid, or tissue through the vagina (though bleeding does not always signal a miscarriage). If you think you're miscarrying, keep in close touch with your healthcare provider. They can prescribe medicine to ease discomfort and advise you to seek emergency care for excessive miscarriage pain or bleeding.
