###Human: Does clear uterus in USG following positive pregnancy test mean miscarriage? ###Assistant: Hi. If the urine pregnancy test was positive then you got bleeding and then, bleeding and uterus empty, then maybe it was a complete miscarriage. Post bleeding, vaginal brown discharge might be infection or remains of miscarriage. To be on safe side have beta hCG and high vaginal swab to exclude infection and pregnancy. Follow with the reports. In case you have pain, immediately report to an emergency gynecologist.  Post-miscarriage or infection. HVS, beta hCG. in case of pain, report to the emergency.
