See below. Symptoms of miscarriage (things you can feel/see) include abdominal/pelvic pain, vaginal bleeding, and perhaps a cessation of pregnancy symptoms (e.g. Reduced nausea, reduced breast swelling/tenderness). Signs of miscarriage (things your md can check) include abnormal blood tests(e.g. B-hcg), physical exam (e.g. Dilated cervix), and ultrasound findings (e.g.Abnormal growth/development). Good luck!
