Hello, Your sonogram findings are suggestive of an incomplete abortion as the sac may have already passed through the open internal os. You should immediately see a specialist for further management. You would need a surgical evacuation if the remaining products do not pass spontaneously. Monitoring under supervision in a hospital is necessary as severe bleeding may ensue if the os is open for prolonged time with a partial abortion. Please maintain genital hygiene and get your coagulation profile done along with blood counts. Take care.
