Threatened Miscarriage

Shaquita
Need help, had miscarried in January at 8wks and 3days with a loss of fetal heartbeat. I started spotting, for two days , went to the er on 6/3 at exactly 6wks. They did a B-hGC level test, urine sample, and ultrasound. My hgc levels were 17320, so of course the urine came back positive, but the ultrasound came back with no heartbeat. I go back for a second ultrasound on 6/9 at 6wks and 6days. Can't think straight anymore, I'm constantly thinking and worrying.
