I began bleeding yesterday but it was brown with no pain... a few hours later it was brown and red but add in pain... I go to the Er and they no longer see a blood clot that I’ve had from the beginning, they baby was there (6wks 1d) and in good position however heart rate was only 65, and my hcg levels had only gone up 900 points in 6 days (was 3900). Today I go to the doctor and the baby is still there but no heartbeat can be detected... she said it appears that the sac is not growing at the same rate as the baby and says maybe I’ll pass it on my own this weekend but if not a formal ultrasound will be conducted early next week...

my question- has anyone experienced something similar but the pregnancy survived?! We had a MC at 5wks last month and now this...
