How do i know if i have a miscarriage ? are there signs ? (8 weeks pregnant)

Bleeding: Bleeding, cramping, termination of morning sickness symptoms--if relevant, are some signs. Sometimes, none of these symptoms may be present (e.g. Missed abortion).

Bleeding: The most common sign of an early miscarriage is vaginal bleeding; it may start light and progress to heavy bleeding and cramping. At 8 weeks, a sonogram can confirm a viable intrauterine pregnancy. See your doctor if you have concerns.
