Did I have a Miscarriage 1 – 5 weeks?

Patient: I am a 47 year old woman with an IUD but today I think I might have had a very early pregnancy miscarriage — no bleeding and no pain but something came out when I peed that looked like an embryo. what happened?

Symptoms: Something fell into toilet while peeing – 3/4 – 1″ in diameter blog opaque tannish mucousy/spongy with dark blob and a dark blood colored “string” or vein attached to it. No pain. No other bleeding. Was it a spontaneous abortion? I have no idea.
